ABSTRACT: An instrument is described which is used for investigating trans-
crystallite corrosion of metal subjected to pressures of over 100 atm. The
instrument is equipped with chlorine-silver and nickel electrodes for electro-
chemical measurements. Ten such instruments were placed in an air
thermostat at 320OC; a pressure of 100 atm was created inside the samples
and a stress of about 25 kg/mm2 was set up in the weakened part of the sample.

Tra,uscrystallite Corrosion of Metal in-High-Pressure Boiler Drums and Tubes
The aggressiveness of the medium was evaluated by the time required for
flaw formation in the sample neck. This action was compared with~the. sample
bel~avior in a certainlyinoncorrosive distillate. Effect of the density of
polarizing (anodic or cathodic) current on the time of flaw formation.is
explained. The influence of niter and other salts as well as some organic
substances upon the above process was studied. AnanalysiB of cases of
trans crystallite corrosion of high-pressure boilers is presented. An inference
is drawn that the transcrystallite corxosion is more severe in high--preEsure
boilers than in medium-pressure; flawk are also formed in the drum body when
the boiler -water has a low alkalinity (3. 5 mg-equiv/liter). Methods of
controlling the trans crystallit e'corro s ion are recommended: elimination of
high stresses, nitrate treatment (up to 70 atm gauge), and phosphate-alkaline
purity of boiler water.

ABSTRACT: The main cause of inter-crystallite corrosion of the metal
of boiler drums is the aggressive action on stressed metal
of boiler water concentrate. Damage is promoted by the pres-
ence in the boiler water of corrosive alkalif the concentrat-
ion ofvhich may reach dangerous values because of local
evaporation of water. At temperatures above 300 OC, which
are usually found in high p:cessure steam boilers, signs of
inter-cry'stallite corrosion appear with a 57o solution of
caustic soda.
The most acceptable condition of boiler water v&ich ensui:,;-
the absence of inter-crystallite corrosion in high and super-.'-
high pressure boilers is to maintain in them zero hydrate
i.e. purely phosphate alkalinity. This is achieved by intro-
ducing into the boiler water various phosphate salts of
sodium. The absence of an accumulation of caustic soda in
evaporating water containing purely phosphate alkalinity and

also the ability.of sodium phosphate to passivate steel make
the zero-hydrate-alkaline condition a reliable means of
preventing inter-crytallite corrosion. However, in practice
certain aspects of this practice require to be cleared up.
The maximum alkalinity can be determined on the assumption
that all of the alkalinity is due to the presence of the most
alkaline compound -NaAPOLL, The lower limit is set by the
condition of preventi.Ag 6cale-formation and general corrosion,
for which it is usually taken that the alkalinity titrated
against phenol-phthalein is equal to 9 mg/l (pH approx.10).
A graph is plotted showing the change in the upper limit
of the alkali number of boiler water und LO given conditions
as a function of the concentration of PR . A graph is
plotted of the ratio of the alkalinity to phenol-phthalein
to thattD methyl-orange of boiler water from the salty
section against the value of this ratio in the clean section,
with a boiler pressure of 110 atm. In practice a purely
phosphate alkalinity can only be maintained-in condensing
power stations, the boilers of which are supplied with high
quality condensate mrith make-up from distillate from evap-
orators or de-salted water. A graph is plotted of the
quantity of caustic soda formed in the salty sections of
boilers with different hardnesses caused by the presence of
calcium and magnesium bicarbonates in the feed water. The
data shows that the concentration of caustic soda in the
643
Conceming alkali-safe conditions of boiler water. (Cont.)
salty sections increases with increase in hardn,~ss of the feed
water. A table is given showing the amount of sodium
phosphate which should be added to the feed water for various
degriees of hardness of the water. Tests have established that
if the excess hydrate alkalinity reckoned as caustic soda is
15 to 20% of the sodium sulphate content of the boiler water
the water will be safe in respect of inter-crystallite
corrosion. It is also shown that sulphate in a mixture with
an equal quantity of chloride if their total content is 15
to 20% of the hydrate alkalinity, can also prevent the form-
ation of inter-crystallite corrosion. The presence in the
boiler water of chloride is useful in preventing general
alkaline corrosion.
It is concluded that the condition of pure phosphate
alkalinity of boiler water in boilers without stepwise evapor-
ation is maintained (on the basis of the index given in the
a3:ticle), according to the maxinnim content of excess concen-
tration of phosphates being not above 40 mg/1 reckoned as P03-
4
and a mini mim alkaline number of about 9 mg/l NaOH. Control
over the condition of puiely phosphate alkalinity of boilers
with stepwise evaporation is effected by analysis of the
boiler watex from the last stage of evaporation. The maxinnim
concentration of excess phosphates in this stage should be of

ABSTRALCT: At regional power station No.7. of L6nenergo, a considerable
proportion of the boiler feed-water is condensate returned from
industrial consumers; it contains up to 2 =g11 oxygen and
4 - 5 mg11 COg. The presence of these gases gives rise to corrosion
troubles, which are described. The troubles occur largely on
consumers' equipment where it is not possible to remove the oxygen
and carbon dioxide. Accordingly, ociadecylamine, a film-forming
substanoo, la added to the steam. The main proportion of
Octadecylamine are stated. It is protective because adsorbed
monomolecular film fOrms on metal surfaces wetted by water
containing it. At the power station, octadecylamine was added to
the turbine pass-out steam by means of the measuring device
illustrated in the sketch. This device comprises two tanks, one

power equipment by means of octadecylamine.
Steam is bubbled through the molten mass to pick up the required
quantkty,armaterial. Preliminary operating results can now be
given. The method of injecting the octadecylamine proved
satisfactory in service. When the concentration of the substance
in the steam was 3 - 4 mg/kg, the iron content of the condensate
was reddoed by a factor of 10 to a stable value of 0.05 mg/1 Fe.
This occurred on the third day after the reagent was first used.
There have been no unfavourable effects, except for the appearance
of a little ammonia in the boiler steam. Steam without additive
can be delivered for some hours without ill effect. Attempts will
be made to replace octadecylamines by a cheaper mixture of
polyamine homologues. This met-had of treatment will probably be
useful in other applications. There is I figure.

TEXT: Austenitic steel parts of theraial power equipment have been
subject to a special kind of corrosion in service; this takes the
form of local corrosion cracks under stress. This article
generalizes Soviet and German published work on this subject.
In a onoe-through boiler with super-critical steam conditions of
300 atm and 600*C, corrosion cracking was observed during the-
conduct of speQial tests to investigate salt deposits for which
purpose caustic soda, sodium chloride, sodium silicate and sodium
sulphate were introduced into the feed water in amounts of 100, 200,
40 and 32 mg/litre respectively, The tests lasted for 3 to 4 hours
with each solution, The steel in question was grade -3M-257 (EI-2057)
Damage of a transcrystallite character appeared on sections of
pipework subject to severe stress. The damage occurred after-about

and so these should be carefully heat treated to remove, the
stresses before use. In the operation of water purification
systems, the instructions should be stricAly observed and in
particular correct regeneration 6f the anionite filters is
essential. If caustic soda or other non-volatile alkalis get into
the feed water they will cause corrosion cracking of austenitic
steel in a very short period of time, To avoid corrosion
cracking, the stresses on the metal should not be excessive,
particularly varlable stress6s. and the i%!orking atedia that comes
into contact with the metal should be of appropriate purity,
Austenitic steels can also be subject to cracking in acid
solutions but this question is not yet fully understood, There

TEXTs A method used to estimate the resistance to corroBion of steels was
suggested by the TeNlITULSh. The deterioration of the plastic properties of the
metal in liquid corrosive a-uSetances is compared with the deterioration
established when tests are performed in air with the state of the sample
slirface after the toot also being considered. As this method given no specific
data concerning the type of corrosive substance, corresponding to to were
performed in this case with an austenite steel of the type lKhIONMU substances
with a weak corrosive action. Experimental conditions and results obtained are
given (Table). The samples were submitted to several preliminary thermal
treatments before testing. It was found that the afore-mentioned toot method
cannot be used in substances with a weak corrosive action in which the
extension of cracks formed by corrosion is very small (as compared to the
elongation rate of the sample). There are I table and 2 Soviet references.

TEXT: The authors give examples of rapid cracking of stressed
austenitic steel boiler tubes irt contact with water containing salts
(Refs 1-3). The object of the present work was to find the chloride
concentration limits at which cracking of type lXl8Hg'r (lKhl8N9T)
stainless steel in the austenitic and work-hardened states is either
eliminated or greatly retarded. Specimens were contained in sealed
190 mm long stainless steel capsules together with 100-110 ml of
the test solution. Specimens consisted of rolled 75 X 10 X 2 mm
plates which were assembled in pairs2 clamped together at each end
and separated in the middle by a rod (Fig.2), to give the required
Stress (somewhat over yield-point strength), clamps and rod being
also of lKhl8N9T steel. The filled capsules, which had been
de-aerated and sealed) were kept at 370 OC in an air thermostat

(Fig.1). Each capsuie contained tvo pairs of specimens, one pair
being of non-work hardened, the other of 30% work hardened steel.
Pressure (200 atm) was directly measured in one of the capsules.
Test duration was 2000 hours. On completion, specimens were
subjected to metallographic examination, one of each pair being
further bent through 900. One series of tests was with chloride
ion concentrations of 0.01, 0.02, 0.11 107 100, 1000, 10 000 and
100 000 mg/litrei and a further series with 100, 200, )+oo, 6oo,

oxygen content 0.02 mg/litre. Both these were varied in a few of
the capsules to find their influence. Results are tabulated and
typical microstructures are shown in Pigs 3-6. F19.3 shows Initial
microstructures of the work-hardened steel; Fig.4 those obtained
with various chloride-ion concentrations. In Fig.5 (extreme left)
the microstructures obtained after testing at pH = 11 and with
different oxygen contents are shown. A faulty capsule produced
evaporation of the solution, giving particularly severe cracking

(Figs 6 and 7). The work showed that stress corrosion is
stimulated by both chloride ions and alkali and that work-hardening
is a major factor (the 30% work hardening used in the tests would
be quite inadmissible in practice). A chloride concentration of
1000 mg/litre produced stress corrosion of the work-hardened
material, further concentration increasing having no further
accelerating effect. Cracks formed both in stretched and
compressed portions of the specimen. The authors emphasise the
importance of metal quality and design factors in preventing stress
corrosion in power-station plant.

TEXT: It was attempted to determine the role of the salt composition and
heat-treatment ~(Cl- and 02) in the development of corrosion under stress in
steels of various grades, among them also in specimens of welded steel. Cracking
of austenitic stainless steels as result of corrosion under'stress takes place
in the water containing Cl- and molecular 02. The intensity of corrosion under
stress depends upon the pressure (temperature), increasing considerably with the
temperature raise. In media with increased Cl content the welded specimens of
austenitio stainless steel are more sensitive to corrosion under stress. Welded
joints of austenitio stainless steel should not be used in the direct flow

steam generators for the purpose of lowering the Cl- ooncentratioil is complate
chemical desalting of the water. Before the water is fed to the heating surface,

TEXTa Stress-corrosion cracking of austenitic stainless steel

Soviet Union and abroad), where they'are used in the steam'

prompted the present authors't6 undierthke the investigation

on tubular specimens, tested on equipment designed to simulate

filled with the appropriate solution (hot or cold) under pressure
of up to 120 atm were stressed in tension# and either time-to-
rupture was determinedg or the extent (if any) of cracking was
periodically measured. The concentration of NaOH in the test
solutions varied between ki and 40 000'mg/-I., the Cl- concentration
in the NaCl solution varying between 0.3 and 150 000 mg/t. (In
some tests hydrazine was added to the NaCl solution). Solutions,
both deaerated and saturated with oxygen, nitrogen or argong Were
tested. The effect of stress concentration was also studied by
using specimens with a sudden change in the cross-section area.
Finally, the effect of exposure to the corroding medium
alternating with dry periods was studied. The results can be
summarised as follows. 1) Under certain conditions, NaOH
solutions can cause stress-corrosion cracking of steel lKhl8NqT,
even when the latter is in'the fully austenitic state.
2) A 4% NaOH solution (pH = 14) can cause cracking of this steel
or cause the development of leaks in faulty portions of a component
in a time as short ap several hours. 3) No stress-corrosion
cracking was observed in specimens stressed for 900 hours at

30 kg/mm2 In contact with NaOH solutions of pH = 11, 1Z or 13, at
310 OC and under a pressure of 120 atm. This means that failures
due to stress-corrosion of steel lKhl8N9T components in heat
exchangers are most likely to occur in the regions of high NaOH
concentration. 4) The rate of stress-corrosion is decreased when
large quantities of oxygen or nitrogen are present in the NaOH
solution. The time-to-rupture of the steel studied, subject to the
action of a 4% NaOH solution with a nitrogen content of 1100-2000
m9/0 is 3-20 times longer than that in a solution with a nitrogen
content of 15.8 mg/t only. The effect of argon Is similar, but
not so pronounced. This is illustrated in Fig.4, ahowIng the
strain/time (mm/h) curves for specimens tested under a stress of
35 kg/mm2 in a 4% NaOH solution, non-deaerated (curve 1),
aaturated with argon (curve 2), and saturated with air (curve 3).
5) Chlorine ions cause stress-corrosion cracking of steel
lKhl8N9T only in the presence of oxygen, the rate of corrosion at
a given oxygen content increasing with increasing Cl- concentration.
When both oxygen and depolarising action of the H+ ions are absent,
no stress-corrosion of steel lKhl8N9T takes place in aqueous

solutions of NaCl, with the Cl- content of up to 150 000 mg/f.
6) In the presence of traces of oxygen, Btress-corrosion of the
steel studied can occur at both low (100 mg/,E) and high
(150 000 mg/V Cl- concentrations, but only if other contributing
factors (such as non-uniform stress distribution, local'dam-a-ge of
the protective oxide skin, etc.) operate. 7) At higher oxygen
r,ontentB, stress-corrosion cracking of steel IKhl8N9T can occur in
water (at 310 OC and under a pressure of 120 atm) with a Cl-
content as low as 20 mg/ Thus, specimens simultaneously
subjected to stress (3510. kg/mm2) and to the action of a sblution-
(at 120 atm and 310 OC) containing 20 - 100 000 mg/t Cl- and
4P mgIC-02, can fracture in several hours. 8) Addition of up to
15 mg/t, hydrazine has no harmful effect, no crack-1;_ng having been
observed in specimens tested for 3590 hours at 310 '.C and under
120 atm in a solution containing 100 mg/t Cl- and 15 mg/t N2H4.
9) Other factors (the Cl and 0 concentration) being equal, the
rate of atress-corrosion cracking of steel lKhl8N9T is increased
approximately twentyfold under conditions of exposure to the
corroding medium alternating with drying.

It was conbluded that, if there is a possibility..of steel lKhl8N9T
into contact with a corroding medium of the type studied,
the bends in coiled tubes should be subjected to, an austenitising
treatment, and that no surface defects with residual tensile
stresses, not removed by appropriate heat treatment, can be
tolerated under these circumstances. The results of the present
investigation indicate also that metal-liquid-gas and not

ABSTRACT: In tubes exterior electrodes there exist two discharge stadiums:
a stable and an unstable stadium. In a series of tests with
neon tubes it was investigated with which processes the formation
of current impulses is connected for unstable discharge. It was
stated that it essentially concerns processes on the tube wallao
Furthermore the influence of radiation with red lines of the
neon spectrum on the current impulses taking place before the
discharge was investigated. It appeared that the origin of the
current impulses for small voltages essentially depends on the
metastable atoms while for high voltages the metastable atoms
are not important. The authar thanks Professor V.A. Kaptsov.

ABSTRACT: Neutron activation analysis was used to determine various elements in Kuna-
shak and Pervomayskiy village chondrites. The samples were irradiated Trith a neutron
flux of 1.2 x 1013 n/cm2 see. The content of Eus ~c, Ba, and U in the clear varieties
of chondrites of olivine-hypersthene composition generally corres-oond to the average
content previously found in chondrites 5f this type. The concentration of Eu, Ce, and
So in hypersthenic chondrites is higher han in enstatite chondrites. In noyLiapetic
fractionu of the invpstigated meteoritesMas compared to their unseparated samples, the
content of Ce, E-_ an,- So is higher, owing to the lithophilous character of these ele-
ments. The con-z-entrr'%'1ion of EV, So, Ba, and U in the dark and clear varieties of Kuna-

ABSTRACT: Polychelates of copper synthe3lzed:from sodium bis-dithlocarbamates
containling a Cu,(SS) chelate unit were Investigated by X-ra*y spectral analysis. The
optimal conditions for the study of the fine structure of the principal K-region
i absorpt,ion of copper In ~olychelates are obtained by working with absorbents having
a density of 3:5-5 mg/cm ; for the study of the fluctuation In an ultra fine struc-
2 ~
ture this should be 10 mg/cm . The data on the: K-region absorption of metallic
copper,obtainedi'in these experiments were in good agreement with the spectrum re-
gistere~ by a dc?uble-crystal spectromet Ier. The' reproducibility of deta,l 'n three
paral]61 experiMents (tile nts lay on a single curve) for polychelates with two
different radlc~ls R H ~21and

the general form of the long-wave strupture of,the spectrum was found to be essen-
tiallyiiinlependent of the change In he Ionic charge* It depended rather on the

this bond of th? electrons with p-symmetry. Upon transition from the spectrum of
the mei6l to that of the oxide, there is a regular shift (- 1.5 e.v.) of the spec-
trum toward theishort-wave side. It can be assumed that the valence of copper in
the polymers st6died is close to unity. Analyiis of the long-wave fine structure
of the'X-ray K-S'pectra of copper In po.lychelatiDs In comparison with the spectrum
of the~metal revealed a change In the valence !of copper atoms in polychelates de- .
pending. on the organic radical in the polymer chain. This change can be due to
change in the degree of overlapping of the sp-functions of electrons producing
the bond between the copper atom in the chelate and additives, such as sulfur
atoms. in polichelates containing R4 and R5 aromatic radicals In the polymer
chain, the absorption spectra show a decrease in Intensity.in the Initial and me-
dium regions, as compared to those of metal. in the spectra of polymers contain-
ing 112''and R3 organic aliphatic radicals, the Intensity of absorption Is Increased
in the5e regions. The difference In the effect of aro'matic and aliphatic radicals
in the, polymer,chain on the nature of the reaction of copper with the.additives In
a' chelates Is also revealed by the change in the catalytic activity of these
ychelates. ','The authors thank V. It Petrosyan for supplying the copper fol I."
