PERIODICAL: Stall, 19599 Nr 9, pp 821-827 (USSR)
ABSTRACT: In view of some difficulties in piercing tube billets
from some alloy steels and a high consumption of metal
in subsequent rolling, the production of tubes from such
steels by atomic hydrogen welding of strip should be
more economical. After investigations of the process by
TsNIIChM and the Moscow Tube Works on an industrial plant
for the automatic atomic hydrogen weldi" of tubes was
developed. Conditions of stability of welding arc on the
diameter of electrodes and their holders supplying
hydrogen - table 1; the dependence of electric
parameters of the arc on the rate of the supply of hydrogen
and thedistance between the centres of electrodes - Fig 3
and 4 respectively. The installation for the production
of alloy tube consists of a modified tube forming stand of
the type 10 - 60, six arcs automatic welding head with a
Card 1/2 control panel, welding transformers and a system of power,

TITLE: Microstructure and mechanical properties of extruded TGM2A molybdenum alloy
SOURCE: Metallovedeniye i termicheskaya obrabotka metallov, no. 12, 1966, 44-48 and

TOPIC TAGS: molybdenum alloy, temperature dependence, tensile strength, metal ex-
trusion, metal grain structure, metal recrystallization / Ts142A molybdenum alloy
ABSTRACT:
TsM2A molybdenum alloy ingots (0.07--0.3% titanium, 0.07---0.15 Zr, impurities
not exceeding: 0.003% oxygen, 0.005% nitrogen, 0.001% hydrogen, and 0.004%
carbon) 78 mm in diameter were extruded at 1000-1600C into bars 20--45 mm in
diameter, i.e. , with respective reductions of 94-68%. The grain size of the
as-cast alloy was 2 mm and up. In the extruded alloy, the grains became
oriented in the direction of deformation and were elongated, with a fibrous
structure. Extrusion at 1000-1150C with a reduction of 68% did not eliminate
the cast structure. Only extrusion at 1300-1600C with a reduction of 75%
eliminated the cast structure completely and reduced the grain size to L
0.05-0.15 mm. In alloy extruded at 1600C, a recrystallization was observed.

scme chemists maintain that these catalysts in eckbination with a reagent pro-

deicribes his experiments in detail and s-1-ates that the dimerization of Isobuty-

cor-rd-Inate compounds with isobutylene. In addition the catalytic aclivity of
H20 - BF3 has been ascertained quantitatively, Kinetic principles and findings ob-
talned in regard to acidity function indicate that the catalysis Of (C2H5)20 - BF 3
yields protons to the reagent and that these campounds themselves cannot be re-
garded as strong aprotic acids. The decomposition kinetics of HCOOH in presence of
BF3 is also investigated. No personalities are mentioned. There are 5 Soviet refer-

ABSTRACT: The investigation discussed in this paper takes into account
also the variation of volume. In the overwbelming majority
of cases the volume practically does not vary if two or more
components are interchanged. In the first approximation it
may therefore be assumed that the volume of the condensed
phase is an additive function of the volumes of the non-re-
acted substance and of the condensed remainder. The volume
of the liquid phase may be considered to be a linear func-
tion of the "degree of conversion" (glubina prevrashcheniya).
If the volume is variable, the reaction of the nth order

variation for a total decomDosition. This reaction is reduced
to the equation of a simple monomolecular reaction if the
variation of the volume by the decomposition is sufficiently
hiah. This implies that the reactions of the first order
may proceed according to the monomolecular law and also ac-
cording to the bimolecular law. Also the taking into account
of the volume by the autocatalysis (which is caused ty tlie
final condensed products of decomposition) modifies the char-
acter of the kinetic curves. This case corresponds to the
kinetic equation dVdt - kj(1 -IL)+(k 2a('-")
where a denotes the share of the catalyzer in the condensed
remainder. For p - 0, the last equation is reduced to the
classical. equation of autocatalysis. A diagram shows the

PERIODICAL: Zhurnal fizicheskoy khimii, 1959, Vol 33, Nr 5,
PP 1030-1034 (USSR)
ABSTRACT: The acid function was investigated over a wide concentration
range by using various indicators: 294-dinitroaniline, 2,4-
dichloro-6-nitroaniline, 9,:-C"L-2--nitroaniline, and o-nitro-
aniline. The measurement was ca:vried out by means of the
spectrophe-@ometer SF-4 at room temperature. The compound
(C2H5)2 OBF3 was synthesized In a quartz euvette. Table I

shows the dependence of ig --L- on the concentration of the
CBH+
ether compound for the individual indicators (C B = concentration
of the non-ionized indicator, C BH + - concentration of the
Card 1/3 ionized indicator). The determination of the acid function

The Acid INinction of the System Diethyl Ether - BF3 SOV/76-33-5-11/33
was carried out assuming that the ether compound investigated
is a strong acid and that indicators in strong acids have the
same value of pK B (negative logarithm of the basicity
constant). Therefore, pK B - -4.4 was put for 294-dinitroaniline,
and pKB for the other indicators determined by the usual
method. The possible inaccuracies of the determination are
discussed. T&ble 2 and a figure give the results of the
determination. The reasons for the deviation of the data
obtained from the results mentioned in reference 3 could not
be found. Starting from the equilibrium constant the equation
of the acid function for (C2H5) 2OBF3in (C2H5 )2 0 is deduced:

inert substances which can increase the decomposition rate of
the explosive by converting part of the explosive into liquid
form, deserves particular interest. This case occurs when the
temperature of the respective eutectic of explosive and ad-
mixture is below the experimental temperature. In this case the

TEXT: Since there are no experimental data available on the amount of
heat resulting from thermal decompositio0of explosives, as well as on
the kinetics of heat evolution during the decomposition, the authors
inveatigated the kinetics of heat evolution in the thermal decomposition
of tetryl with a differential self-regulating calorimeter (Ref. 1). The
determinations were made for the temperature range 1300-1550C, with the
weighed portion being such as to permit the decomposition to be regarded
as isothermal. As is shown by the curves (Fig. 1) representing the rate
of heat evolution, the tetryl decomposition has a self-accelerating
character. Table I gives the amounts of heat resulting from thermal

decomposition for the temperature range investigated; the mean value is
341 cal/g. The reaction kinetics of tetryl decomposition is described by
an equation (2) of autocatalysis of the first order which takes account
of the volume change occurring in the course of the reaction. The kinetic
constants (Table 2) were determined from equation (2), and the values of
the activation energies and the factors of the exponential fanctions from
the temperature function of the rate constants. The kinetic constants
obtained from heat evolution, on the one band, and the weight loss, on
the other, were found to be the same. There are 3 figures, 2 tables, and
4 references: 3 Soviet and 1 British.

pp. 399 - 400
TEXT: Proceeding from experiments conducted by P. F. Pokh!1 (Ref. 1)
the authors investigated whether the burning of dispersed powder par-
ticles occurs in the hot flame zone near the maxi-mum temperature, or
whether its decomposition occurs already on the surface of the powder.
For this purpose an isothermal estimation of the lifetime t life of a
particle is carried out. It was assilm d that the decomposition of the
particles starts at T surf of the surface. Equations are written down
for the burning rate u, for t life' and for x di-sp' the path of the dis-
persed particles. T surf' tlife' xdisp were calculated on the basis of
the experimentally found values for u, and x disp compared with the

following conclusions are drawn: An exothermal decomposition occurs
in the condensed phase, causing the dispersion of a considerable part
of the powder. The decomposition of the dispersed particles occurs
close to the surface of the burning powder with 300 cal/g ard more
being released. The final reaction occurs with the formation of' the
final products, and release of the rest of the heat in the zone of
maximum temperature. There are 1 table and 6 references: 4 Soviet and

TITLE: Thermal decomposition of tetryl at varying m/V values
PERIODICAL: Zhurnal fizicheskoy khimii, v. 35, no. 2, 1961, 306-313
TEXT: A. Lukin and S. Z. RoginBkiy (Ref. 5: Acta chem.-phys. USSR, 2,8,
1935) found a critical ratio to exist between the weight m and the
volume V of the reaction vessel in tetryl (2,4,6-trinitro phenyl methyl
nitramine), in which the slow decomposition passes over into an explosion
under the promoting action of various additions (NO 2 et al.). An exteasive
study has been made of the kinetic rules governing the isothermal decA_
position of molten tetryl as a function of the m/V ratio. The reaction
concerned was examined in a device made from stainless steel, as diagram-
matically shown in Fig. 1. The pressure rise was measured with the aid
of a thin membrane made of stainless steel to which tensometer 5 was
fastened. The change of resistance of 5 was determined by a rr15-2 (GPZ-2)

galvanometer inserted into the diagonal of the bridge. The measurement
was made by the compensation principle. The membrane was brought back
to zero position by introducing nitrogen from bomb 6 into the -.ompensator.
The pressure rise was measured at given time intervals with the pressure
gauges 7 and 8 connected to the compensator. Also a strain gauge was
fastened onto the membrane, to serve as second arm of the bridge and for
a compensation of temperature fluctuations. The clamp 4 (Fig. 2) was
pressed onto sealings made of fluorine-contaiaing synthetic material
3 between flanges 1 and 5, the tubes from the strain gauge were via tube
6 connected to the outer arms of the bridge. The minimum measurable
pressure is 0.1 mm Hg, the reading accuracy on the mercury manometer
+ 0.2 mm Hg. The gaseous products were analyzed for NO 21 NO, N 20, CO, and
C02* Samples were taken by means of traps 9 and 10 (Fig. 1) and cuvette
11. The kinetic curves of gas evolution at 150 OC (Fig. 3) and 1600C (Fig.

are given. The m/V maximum was about 44 times as large as the correspond-
ing minimum; the maximum end pressure of the decomposition products was
about 6000 mm Hg. The curves show that the reaction kinetics is practical-
ly independent of the mass of the substance, and that the decomposition

rate increases at all temperatures with rising m/V. The percent content of
N02 , NO, and condensation products drops with increasing decomposition, while
the percentage of C02 and N2 increases somewhat toward the end of the reac-
tion, and the CO content remains practically unchanged (Table 1). The change
in the number of N02 and NO moles per mole of tetryl as a function of the
conversion degree for various m/V at 1500C is given; ki is the constant of
the monomolecular reaction, k.' that of the autocatalytic reaction, and k, is
* constant depending on m/V, in which connection dj/dt - k, (1 - I )- k@r[(l -7t)
* k3l[(l -q) = k 1 (1 -1) + k2 (1 -7[), where k 2 = k@ + k3' The dependence
of k1 on m/V is shown in Fig. 7. The initial acceleration of the reaction i@/@
correlated with the course of the macroscopic stage of the reaction, which
leads to the formation of a highly volatile product with a catalytic action.
This process is inhibited after some time by the tetryl decomposition. The
further acceleration does not depend on the volume of the reaction vessel,
which is indicative of an autocatalysis by the final condensation products

tion energy and of the factor of the exponential functicn in the Arrhenius
equation were calculated from the rate constants (Table 3), the values ob-
tained for k1 being character-.stic of the monomolecular decomposition,
whereas an activation energy of 37 kcal/mole was found for k 2 with all m/V.

PERIODICAL: Zhurnal fizicheskoy khimii, v- 35, no- 3, 1961, 521-529
TEXT: The authors studied the kinetics of thermal decomposition of trinitro-
phanyl methyl nitramine (tetryl) with exact analysis of the decomposition
products. They recorded the kinetic curves for the gas generation occurring
in the decomposition of tetryl at temperatures between 140.3 and 164.90C.
The nitric oxide content in the gaseous phase increases slightly at the
beginning of decomposition, and then remains constant. The carbon monoxide
and carbon dioxide contents increase at the end of the reaction. An in-
crease in the reaction temperature increases the nitric oxide and nitrogen
dioxide contents. The kinetic curves for the accumulation of N 2f Col CO 2'
and NO are S-shaped. An analysis of the condensed decomposition products
of tetryl shows that the condensed phase contains, besides picric acid,
considerable amounts of 2, 4, 6-trinitro-anisole and N-methyl-2, 4, 6-tri-

determination of condensed products. The products were applied to eilica
gel dyed with rhodamine-6-Zh. The separately isolated products were spec-
troscopically investigated in alcoholic solution in the ultraviolet spec-
tral range@ To distinguish 2, 4, 6-trinitro-aniline from its N-alkyl
derivatives, the infrared spectra were also taken with an HKC-11 (IKS-11)
spectrophotometer with LiF prism in the range of 2.65-3.2 p. Aft@r the
separation, the condensed decomposition products were hydrolyzed to picric
acid, the quantitative determination of which was performed with an CO-4
(SF-4) spectrophotometer. The kinetic curves for the accumulation of
2, 4, 6-trinitro-ariisole and picric acid, as well as for the consumption of
tetryl, are S-shaped. The formation of N-methyl-2, 4, 6-trinitro-aniline
proceeds very rapidly at the beginning of the reaction, and slows down laten
An addition of picric acid was found to accelerate the tetryl decomposition,

PERIODICAL: hinetika i kataliz, v-3, no.1, 1962, liq--46
TEXT: As the literature data on thermal decor--position of
nitrocellulose are contradictory, the authors investi@jated the
kinetics of thermal decomposition of pyroxilin powder within a
temperature range of 140-165 OC. The kinetics were studied by
three different methods: by the evolution of heat in a double
calorimeter (in vacuo and at atmospheric pressure); by changes
in weight on an automatic thermal balance in the presence of air;
and by gas evolution in a static vacuum apparatus with
subsequent analysis of gaseous decomposition products. It was
found that thermal decor-.iposition of pyroxilin powder in axr a5
well as iii vacuo takes place to a certain depth of decomposition
(depending on the temperature) with autocatalysis of the first
order; subsequently the process continues as the first order
reaction. The heat effect of thermal decomposition is

independent of the temperature and is on average about 750 cal/g
which amounts to more than 6U.. of the heat of combustion (about
900 cal/g). on decomposition in vacuo the Iierit effect decreases
to 515 cal/z. In the autocatalysis equation
dj/dt = k 1(1 - Q) + - 0
which describes well this stage of the reaction, kI and k9
were calculated from experimental data. The temperature
dependence of these constants (for heat evolution in air) was
found to be:

C02 increases and that of NO decreases, indicating that the
initially split 'N'02 group reacts quickly with the condensed phase
leading to the formation of nitrogen oxide, carboxyl and carbonyi
groups. The process of decarboxylation proceeds with a lower
velocity than the reaction of formation of ING and develops mainiy
at the end of decomposition when the destruction of the puiymeric
chain is well advanced. The catalytic influence of gaseous
decomposition products is indicated by the fact that the velocity
constant k2 is lower on removal of the gaseous products than
it is in their presence. However, the autocatalysis of thermal
decomposition of pyroxilin was also observed on continuous
removal of gaseous products, indicating that functional groups
(carboxyl, carbonyl, etc.) of the polymeric molecules, formed in
the course of the reaction, also have a catalytic influence.

ABSTRACT: Yttrium and gadolinium borides were synthesized from respective oxides
with amorphous boron at 1400-2000C in a vacuum of 2-5-105 mm Hg. The reaction
MeO + 2B - MeB + BO yielded YB,,, YB6 and YB12 yttrium borides and GdB4 and GdB6
gadolinium borides. Single-phase YB6 and YdB6 hexaborides were obtained at 170OC;
at higher temperature they decomposed into tetraborides and boron. Single-phase YB12
compound was obtained at 1600-1700; at higher temperatures it decomposed into
YB602 YB4 compounds. Yttrium and gadolinium boride powders were then compacted,
sintered in vacuum, and tested. The porosity of yttrium-boride specimens was
22-26%, and that of gadolinium-boride specimens was 30-32%. The microhardness and

bend strength of YB4; YB6, and YB12 was 2850 dan/mm , and 290 dan/cm , 2575 dan/mm2,
and 270 dan/cm2' and 2500 dan/mm2, and 165 dan/cm2, respectively. The microhardness

and 320 dan/cm , respectively. The boride contained almost no impurities. The most
oxidation resistant were gadolinium borides and, among yttrium borides. the YBIZ
compounds. Orig. art. has: 5 figures and 6 tables.

TOPIC TAGS: borideq gadolinium compound, thermionic emission
ABSTRACT: The thermionic emission of the single-phaso compounds Gdb4 and GdE6 and
two-phase compositions GdB4 + Gd203 and GdE6 + B was investigated. The effective
work function 0 t and temperature dependence do /dT 2were determined. GdF4 was found
to have the best emissive properties (j = 0.6B A/cm , 0 = 3.13 eV at 17500K). With
GdB6 on a tantalum sabstratep one can record a maximum emission current of only
1.4 x jo-5 A/cm2, 3.41 eV at a temoorature of 1600'*K. GdB4 is more stable than
GdB6; the latter decompose3 in a vacuum at high temperatures to form GdP4 and B. The
impurities W20@ in GdE4 and B in GdF6 markedly decrease their emission per unit zur-;
face of the composition. In their emissive properties, the gadollnium borides studied-
are much inferior to lanthanum hexaboride, which at 16000K has j = 1.34 A/CM2, @ = i
2.71 oV, and at 18000K j = 7.15 A/=2, @ = 2.85 GV- 7he data show that the emissive
