stressed specimens. Results are shown in tables andschematic
drawings. The following conclusions are made: 1) titanium
welds, tested uniler the afo,Xementioned conditions, have the
same corrosion resistance as the base metal; 2) commercial
titanium and its weld joints are prone to corrosion cracks

PERIODICAL: Avtomaticheskaya svarka, 1959, Nr 8, PP 49-56 (USSR~
ABSTRACT: The article deals with methods of testing corrosion
resistance of welded Joints of aluminum. The authors
wish to ascertain the character of the action of nitric
acid in relationto its concentration and-temperature,
and more precisely define thenecessary preparation of
surface of samples and other experimental conditions
in order to work out -the most acceptable accelerated
method of.testing welded joints of aluminum in nitric
acid. The authors open with a review and critique of'
other work in this field, including that of V.P. Ba-
trakov LTef V.A. Savcheliko ZRef 7 , and P.B. Slo-
myanskaya and A.N. Krutikovl/ffef 1~0~, but they find a
comparison difficult because the methods used varied.

PERIODICAL: Avtomaticheskaya svarka, 1959, Nr 101; PP 19-30 (USSR)
ABSTRACT: The purpose ofithe tests described in the article was
to,determine the mechanical properties and corrosion
~resistance of Welded joints made from titanic alloys
of Types VT3-1, N'T4, OT4 (two-phase), VT5 and VT5-1
(single hase), which are new in general use:.Zlaefs

resistance of the.alloys and their welded joints,
sheet metal 3-3,5nm thick was taken end tests were
conducted on butt-joints by means of various alloys

with the alloys:VT5-1 and OT4 were of the maximum
elasticity (Table 2). G3Fwphs of the mochanical proper-
ties of the metal of the seams under various tempera-
tures are given in Fig 1. The toughness of the alloys
(given in Fig 2) was found to be virtually invariable,
normal-temperature; but at low temperatures (-70 0
C) that of the a1loyq VT5 and VT5-1 decreased (to 2.3-
2.5 kilogrammeter/em') more than in thl case of the
.alloys OT4 and VT4 (4 kilogrammeter/cm Table 3 con
itains the results of tests-on the mechanical 2roperties
of welded butt-joints carried out on 10= thiek metal
by means of Type.VT-1 titanic wire 3mm in'diamater,
with flux Type AN-T1; it can'hence be seen that the
tendency of single-phase seams to friability is due
to their greater sensitivity to hydrogen. It is sta-
ted that the resistance to friability of titanic seams
may be raised by the addition of molybAenum *Z7Ref 5-7.

TITLE: Effect of heat treatment on the corrosion r(isistance of AKg6 alloy
and its welds
PERIODICAL: Avtomaticheskaya svarka, no, 2, 1961, 40-47
TM: T.'ete Mr 6 (WO alloy is an-extensively used alloy that is corrosJor.-
proof In air but not so in sea water. It is used in shipbuilding, apart from
many other applications. It has been known for a long time that Al-Mg alloysidth
above 5% Mg are prone to sea water corrosion after hardening and aging, and the
AMg6 can contain as much as 6.5% Mg.. The described tests were carried out because
of contradictory data in literature on the effect of heat treatment on such alloy
grades. Two studied AMg heats had the following composition: 1) (%) 6.2 Mg,
0.70 Mn, 0.25 Fe, 0.25 Si, 0.14 Ti; 2), 6.5 Mg, 0.59 M", 0.05 Fe, 0.06 Si, 0.10
Ti. The welds were produced with an automatic argon are process, with tungsten
electrodes and filler wire of AMg6. The corrosion test solution was water with
3% NaCl + 11,16 ~HC1; tests were carried out at 200C, for 24 and 48 hours, and the
test techniques corresponding to those described by P. Brenner and W. Roth

[Ref. 12: Recent developments in corrosion-resistant Al-Mg alloys. J. Institute
of ketails, 74,'159, 1947). The results show that the corro:3ion rate rose abrupt-
ly after annealing at 125 _2250CP then dropped, increased t3lightly in the 300
4000C range and decreased again at 500,0C.IThe article includes. photomicrographs
made with an electron microscope. It was evident that metal subjected to the
effect of high temperature (above 500 OC) did not corrode, and that a second phase
of peculiar appearance segregated on the grain boundaries in a continuous grid.
Judging by the data of other investigations it was the 61 phase that is instable
and is converted into the equilibrium J&phase at higher temperatures. The
phase has a higher negative potential than- the solid Mg solution in Al and the
usual a and besides the solid solution loses Mg at its formation. The consider,-
able pdtential difference in an electrolyte causes rapid decomposition of the
boundary grid and a separation of whole grains from the metal. Apart from this,
the behavior of metal appears to depend somehow on the state of the grain bound-
aries themselves, as this was noticed by P. Erdmann-Jesnitzer [Ref. 15: Inter-
,kristalline Korrosion und Korngrenzenaufbau, "Werkstoffe und Korrosion". 9 N.,
1, 7P 19581., It is concluded that the alloy tends to intercrystalline-corrosion
after.10-hours at 125-2250C, and long heating in this range must be avoided,

TrI.M., On the method of:hvestigating the tendency of welded joints to
caustic embrittlement
PERIODICAL;* Avtomaticheskaya svarka,, no. 4, 1961, 86 87
Mr: Brief information it given on a new method of caustic embrittlement
tei5ts requiring no special tension devices. Formerly, the Ihstitut elektroavarki
im. Ye. 0. Patons. (Electric Welding Institute Im. Ye. 0. Paton) employed test ape-
cimens consisting of ribs welded to plates, and then the plates joined by butt
welding, and later horseshoe-shaped specimens, or.specimens loaded with a special
device. Reference is made also to a recommendation of G. L. Shvaxts and M. M.
Kristall to use a specimen 100 by 20 by 8 (mm) -in size, cut from welded plate with
removed projections and loaded,by the application of a bending or stretching force.
The authors have used a method requiring no application of devices for the load-,
ing. Detailed information on the new technique will be published later in "Avto-
maticheskaya svarka". The method consists in using welded plates 500 x 400 x 6
(rmn) in size and. holding them in a boiling solution of.45% calcium nitrate and

35% ammonium nitrate until the appearance of cracks. The solution is being con-
ventionally used for -testing the tendency of steel to caustic embrittlement. The
article includes a photograph of a cracked specimen, Heat treatment had a high
effect on the results of the tests, e.g. in one specimen that had not been heat-
treated the crIack appeared after 24 hours, in two others after 48 hcrars, and in

MUODICAL; Avtomaticheskaya svarkaf_ no. 5, 1962, 36-43
TEM., Since equipmentused in the altuninwri industry has to be frequently re-
paired because of cz.ustic cribrittlement of low-carbon and low-alloy steel, and
silice.alternative s!;eels cost too much, the effect of stress-relievinff on the
resistance of low-dUoy steel welds to caustic cmbrittlement was studied, usin.g
a method described 'oy T.W. Green and A.A. Holzbaur ("The Welding Journal", No. 3,
1946). The ex
perimental equipment comprised a carriage with 4 gas burners pro-
ducing a 120 mm-wide flame, and a water-cooling device 150 mm behind the flame.
Five steel grades were tested. Calcium and ammonitun nitrate solutions were
used for corrosion tests. The electrode potential in specimens was measured.

metal was 1.7 : 3.0, and the highest potential was found in the 14f-2 (14G2)
steel - 61 mv before heat treatment, and 30 mv after. The anode zone was always
revealed directly at the welds and appears to be the result of stress concentra-
tion. It is presumed that caustic embrittlement of low-carbon steel. in strong
alka.1i solutions begins with the destruction of the protective surface filin,
and this process is most intensive in metal at welded jointsjwhere the anode
potential is highest, b= weld defects such as pin holes, slag inclusions, or
spills also cause stress concentration and anode potential. Conclusions: (1)
Thermo-mechanical treattnent considerably improved the resistance of low-carbon.
and low-alloy steels to caustic enibrittlement; (2) welds in 19 1- (19G), M 16 e
('1UGS) and C-.3 (St.3) steels have better resistance to caustic embrittlement
than [A (1-1) and 14 r 2 (14G2) steels; (3) the result of electrode pctential
.,.measurements show that residual welding stresses intensify the anode processes
in the weakness zone. There are 7 figures and 3 tables.

ABSTRACT.. The derivatives of phenylacetic acid were investigated in
detail as many of them are physiologically active bodies with
the capability of accelerating the growth of plants (reference
1). The authors intended to carry out-the synthesis of phenyl-
difluoroacetic acid and of its derivatives not mentioned in
publications. For this purpose they began- witli the re-
action of the nitrile of plienyldichloroacetic acid with anti-
many trifluoride. The benzylcyanide was used as initial pro-
duct. It was chlorinated according to Claisen (reference 2)
--ulfurylehloride (reference 2) and then fluorized with
antimony trifluoride. Here it was observed that the cyano-
group was not effected and was not substituted by fluorine.
The reaction takes place according to the following reaction

The nitrile obtained was in cold state converted to the amide
by the action of concentrated sulfuric acid; this amide furni-
shed the pheny1difluoroacetic acid when heated with 10% potash
lye. When this acid is nitrated the m-nitrophenyldifluoro-
acetic acid is formed - These two acids are rather strong. In
the reaction of the nitro compound the m-amino derivative was
obtained. The silvery salt of pheny1difluoroacetic acid re-
acts with iodine in a peculiar way forming 6J,4j-difluoro-
benzylester of phenyldifluoroacetio acid according to the
mentioned scheme 2. The experiments to,form this reaction in
another way to obtain pheny1difluoroiodomethane were not suc-
cessful. There are 2 references, I of which is Soviet.

~ABSTRACT: p-nitrophenylhalogenmethylcarbinols are intermediate products
in the synthesis of the synthetic antibiotics of synthomycin
(sintomitsin). The synthesis of p-nitrophenylchloromethyl-
carbino! (I) was first carried out from styrene by V. A.
Mikhalevand co-workers. The chlorohydrin of styrene was
acetylated, the acetyl derivative was nitratedg the p-isomer
was separated from the obtained mixture of nitro products
and was saponified to the compound (I). It was of interest
OR to the authors to carry out directly
the nitrification of chlorohydrin styrene.
'They found that an the addition of this

methylcarbinois form (Ref 2). The nitrogen ether of ",he
p-nitro derivativewas separated from the mixture by crystal-
lization. In order to check the structure this product was
oxidized with permanganate to p-nitrobenzoic acid and was
identified with the above mentioned product (I) by Mikhalev;
the structure of the m-isomer was determined ir. an analogous
way. Por the synthenis of p-nitrophenylchloromethyloarbinoI
it was necessary to saponify the nitrogen ether, which, ac-
cording to existing data in publicationsy was expected to
be very difficult. A perfect saponification (9o ~, yield)
to carbinol Was achieved by the authors only by heating
the above mentioned ether with a great excess of concentrat-
ed hydrochloric acid,6:.They further found that it is useful
to take a.mixture.of hydrochloric and phosphoric acidq in
which case a complete saponification is achieved with a
much smaller amount of acid. Aa'h peculiar fact, the saponi-
fication does not take place with phosphoric acid alone.
Besides the mentioned methods of saponification also others

ABSTRACT: The reaction, investigated according to reference
of the aliphatic diazo-compounds with phosphorus
halogenides showed,that,phosphorus tri- and phosphorus
ethane at -6
pentachloride react with diazon. 0 %-40'.
In ",he case of theforpier chloride, the reaction ends
at the sta .ge of the-monoalkyl derivative, with the
formation of chloro-methyl-phosphorus dichloride; with
~phosphorus penta chloride it continues up to the tri-
alkjll,derivativ;3, trichloro-trivethyl phosphine. The
investigation of the reaction of arylphesphorus tetra-
chloride with~diazomethane suggested itself. It vias found
that'phenyl-phosphorus tetrachloride reacts most read4ly
with. it at -400. After.hy4rolysis, a,C4W'- dichloro-
.-.Card 1/3 dimethyl-phenyl-phosphine oxide was separated out,

Gohipo-and M, separated out in colorless prisms, is
difficultly soluble in water and benzene, and solves well in
alcohol and acetone. Its chlorine atoms in the chloro
methyl groups do not react easily. The nitrification of
(I) is achieved by means of a nitrating mixture, the
nitro group entering, according to Sandmeyer(Zandmeyyer),
into the meta-position I (Reaction pattern 2). The same
end product (IV) can also be obtained by the counter-
-synthesis 3. Thus the group
