ABSTRACT: A theoreiical study has been made of thermal explosion with varying tem-
perature of the surrounding medium. The parameters of thermal explosion Vere cal-
culated for monomolecular, bihLolecular, and autocataly-tic reactions. Exact; and
approximate solutions were obtained by numerical integration and by pseudoisothermal
approximation, respectively. A plot of explosion temperature vs the rate cof heating
showed that.in monomolecular reactions, the explosion temperature decreases with in-
creasing rate of heating to the critical value corresponding to static conedtions.
In autocatalytic reactions, depending on conversion, the explosion temperature either
first increases and then decreases or it only increases. Orig. art. has: 2 figures,

ABSTRACT: The first part of this paper (Nauchno-tekhnicheskiye problemy gorenlya i
vzryva, 1965, 1) investigated thermal explosion conditions during the heating of the
surrounding medium. The present article studies these conditions for the case of
cooling. The explosion pattern and its basic characteristics are studied. The
derivation of the approximate solution to the problem, the results of numerical computer
integration of an original system of equations, and a discussion of the critical heating
rate, pre-explosion reaction intensity, pre-explosion heating, and of other pertinent
parameters describing the events are given. The article concludes with a discusalon of
the application of the linear cooling method to the experimental study of the thermal
explosion of strongly self-accelerating reactions. The authors thank A. S. Ukolov
for several computations carried out during the investigation. Orig. aiff._TE`s*~ formulas,

TOPIC TAGS: chemical explosion, combustion kinetics, temperature distribution
ABSTRACT: Equations for thermal explosion during heating are numerically solved
with regard to temperature distribution. The paper is a continuation of previous
studies (A. G. Merzhanov, A. G. Strunina, Scientific and Technical Problems of Com-
bustion and Explosion, 1965, 1; A. G. Merzhanov, A. G. Strunina, Z. B. Mayofis,
Scientific and Technical Problems of Combustion and Explosion, 1965, 2) and the no-
tation is the same as that used in these articles. The problem was solved on a com-
puter. Analysis of the numerical solution shows that ignition under dynamic heating
conditions is completely analogous to the process under static condition-;. The

basic parameter in defining the exchange conditions is the rate of heating W.
Curves are given showing nonstationary temperature profiles for a monomolecular re-
.action at a Biot number of infinity and various values of w. Four regions are dis-
tinguished with respect to heating rate: 1. ww*l -_ the limiting
region of ignition. A table is given showing the upper and lower critical heating
rates for various Biot numbers. The data show that the spontaneous combustion re-
gion is considerably wider under dynamic conditions than for static processes. This
is due to the fact that conditions for generation of a heating maximum are less fa-
vorable in the dynamic process because of the temperature increase on the! surface of
the system. The region of spontaneous combustion under dynamic conditions increases
in latitude with a reduction in the Biot number. These data are compareC with solu-
tions disregarding temperature distribution. Curves are given based on both systems
of equations for the temperature of onset of combustion as a function of heating

of spontaneous combustion. Thus temperature distribution may be disregarded in this
region. Orig. art. has: 4 figures, 1 table, 4 formulas.

ABSTRACT: The theoretical principles. of thermal explosion postulated in previous
studies of this series are verified by experivonts 77=eating and cool--'ng of
-te tryl,~ nitrocellulose I and DIIIA charges in a reaction vessel with a low heat-
tr&n.,;fer coefficient-and witb a linear temperature increase in the surrounding medium.1;
For tetryl charges with a 0.8 cm diaiae-~ev and a critical temperature of 146C, the
heating rate VUried between 0.8.and 17-40/hr. The explosion occurred only at heat-
ing rates above the critical heating rate (2.4'/hr); at heating rates below the
critical, tetryl decomDosed'without an e.-qilesion. When the heating rate increar-e(I
from 0.8 to 1.90/br, the ma~iLmtm temperature increased from 5.3 to 12.2C. Th~

ABSTRACT: The conditions under which the thermally stable explosive No. 211
(unspecified) may be use4 e.g., under elevated temperatures and pressures i deep
cdl wells. were studied experimentally and theoretically. Critical igniti~'.Aempera-
ture- T*, critical induction period t*, and critical charge diameter d* weFe- measured
in a constant temperature reaction vessel with a layer of sand between the charge
and the reactor walls. Equations were derived for calculating the critical tempera-
tur., ve No. 2 and for calculating the critical induction period for
,es of explosi
the..explosive at any temperature. The upper temperature limit for the application
of No. 2 decreased with.increasing charge diameter from 190 at d - 1.6 cm
to q75C at d = 5.0 cm. The experimental data are in good agreement with the
calculated data. Since the induction period increased with increasing charge diametar,

large diameter charges are riot practicable. it is shown that the explosive
system has a "memoi-
y effect", i.e. , the self -ignition delay in charges kept A
certain temperatures for a second time, t2 = t ir4 -tj . where ti is ;the i.7iiticn delay
time after the first thermostating. It is shown that the explosiofi energy and
detonation velocity of the charge decreased with increasing residence time of the
charge (in an oil well), and the sensitivity of the charge to impact increased
with the residence time. Orig. art. has: 3 tables, 3 figures, and 4 formulas. [PSI

Investigation of the High-speed Steel R18

ABSTIZACT: For the determination of the residual austenite in R18-steel
the method of magnetic metallography suggested in reference 1,
was applied. The method is based on the fact that colloidalmagnetic
particles which are applied to the ground section in the
form of a paste are accumulated at the ferromagnetic phases
while the nonmagnetic phases remain free. Austenite and the
carbide phase of R18-steel are nonmagnetic and therefore re-
main free of colloidal particles; however, they can be dis-
tinguished from one another as they exhibit different struc-
tures. Test results showed that UP to 30aA of the residual
austenite 18 present in the microstructur8 of a steel temper-
ed at 1,280 . After treble drawing at 560 there is no more 0
austenite visible in the steel (Fig 2). On tempering at 11310
the residual amount of austenite is considerably increased.
Determinations of the residual austenite were also made on
Card 1/2 finished cutters, and it was established that among other

TEXT: The author describes a method of rating the axially-symmetric
bend of disks under the effect of outer loads and non-uniform heatine of
the disk along the radius. The tension effect on the bend is not taken
into account, temperature variations along the radius are assumed to be
linear. The differential equation of the bend is written down for plates
of constant thickness and is solved separately for the outer loads and for
the non-uniform heating of the disks along the radius. The disk profile
is broken up into the necessary number of sections of constant thickness,
for each of which the magnitude of bending moments and deformation are
determined.

ABSTRACT: The problem of torsional oscillations of blades in
axial compressors and turbines is riot as expertly
explained as the problem of transverse (bending)
oscillations, the reason being that the foriner are
evoked by small forces and result in only small stresses.
The authors of the criticised article arrive at a
different conclusion, viz: that "normal stresses-arising
in torsional oscillations are comparable with and, in
certain cases, even substantially larger than the normal
Card 1/4 stresses produced in bending". This conclusion would

SOV/147-59-2-20/20
Criticism of the Article by A.M.Soyfer and V.N.Buzitskiy
"On the Normal Stresses Arising in the rorsional Oscillations of
a Blade"
be a very important one if it were true. However,
the low level of the experimental technique and the
presence of errors in the article do not allow
acceptance of these findings of the authors. After
questioning the work, reasoning and theoretical basis
of the above conclusions (there are in all some
13 queries) the present author advances some original
explanations of the work carried out by the previous
authors (which was left unanswered in their article).
This is done on an example of a blade (fixed at one
end) of a constant cross-section along its whole
length and being acted upon by a uniformly distributed
twisting moment. By Ref 3, the differential equation
of torsion is given on p 160, EIW being flexural-
torsional rigidity and GIT - being free torsion
rigidity. Its solution, as well as the normal stress
cz, are then quoted and this stress is then presented
Card 2/4 in the form of graphs (Fig 1) for various values of the

sov/147-59-2-20/20

a Blade"
parameter k =-GIrt 2 which characterises the strength
EIw
of the blade; (the graph gives the relative values of
the stress, i.e. referred to the stress at the root).
Next, the corresponding formulae for 0 and @I' for the
case of the first mode of torsional oscillations is
quoted from Ref 4 and utilizing the latter the normal
stresses a2z are obtained (Fig 2) for various values
of k. From the analysis of these curves it is seen
that even in the case of a uniform blade maxima of
stresses may be expected and what is more there are
sections(other than the free end) where the normal
stress vanishes. The actual position of that section
depends upon the parameter k. To explain this
phenomenon, Fig 3 is used representing 9 = f(x).
The dotted curves apply to the limiting cases
EIW =OandGIT=O (i.e. k=co andk=-O).
Card 3/4 For any finite value of k there will be a point of

a Blade"
inflection M, as shown on the full line graph for
k =-5; this point corresponds to 0 O,i.e.oz = 0.
Though in blades with variable cross-sections the
stresses will differ from the above distribution for
a constant cross-section blade, the character of the
stresses, however, may be expected to be similar.

ABSTRACT: Tests over a wide range of temperatures and H2S04 concentrations showed
that chlorine consistently retards the corrosion of titanium, which increases rapidly
with temperature (see Fig. 1 of the Enclosure). In the presence of chlorine, eorrosion
also increases rapidly with 112SO concentration, but In its absence the corrosion rate
passes tbrough maxima at about tO and 80% %S04. The authors then went on to study
corrosion by organic acids, which are weaker than the mineral acids, since such organic
acids as acetic acid, formic acid, oxalic acid, maleic acid, phenoxyacette acid and

several others strongly corrode cast iron, steel and other metals. Tests with titanium
showed strong corrosion In oxalic acid (100 mm/year, or the same as in 20%, hydrochloric
acid). Low stability of titanium was also noted In formic acid, tartic acid ard citric
acid, as well as In mixtures of glacial acetic acid with acette anhydride. Strong corrosion
of titanium was observed in hot solutions of oxalic acid and tartaric acid, while the
highly aggressive properties of citric acid are explained by the solubility of the compounds
in water. These results indicate new possibilities for the use of titanium equipment where
hydrochloric, hydrobromic, hydroiodic and sulfuric acids containing free halogens par-
ticipate in chemical reactions. Titanium tips are employed on thermocouple~3 working in
chlorination processes. Laboratory tests have shown the harmful action of alternating
current on titanium in acid solutions, but a titanium bubbler has been worldqg success-
fully in the production of chlorine. It is also advisable to use titanium for the treatment
of organic substances with bromine tn water. Orig. art. has: I figure and I table.

ABSTRACT: Halogens generally increase the corrosion of Iron, copper, nickel, leads
and other metals In hydrochloric acid. Only tantalum, a very costly and rare
metal, has high stability, although titanium has sufficient stability In hydro-
chloric acid up to a concentration of 5%. The present paper considers the effect
of halogens an the chemical stability of titanium in halo acids. Titanium corrodes
insignificantly in halo acids at room temperature, but at 90C corrosion reaches
tremendous proportions (about 400 mm/year in hydrochloric acid and 72 mm/year In
hydrobromic acid). In all cases, addition of halogens to hydrochloriq: and hydro-
bromic acids was found to lower the corrosion rate of titanium, although increas-
in e temperature lowered the protective capacity of the halogens. Chlorine,

bromine and iodine decreased the corrosion of titanium to the same degree. The
view that titanium reacts with chlorine, bromine and Iodine only at high tempera-
ture Is incorrect, since several recent publications have reported that titanium
reacts rapidly with chlorine at room temperature and even at -18C. Tests by the
authors showed that VTJ titanium sheets ignite In chlorine gas at ro*om temperatures
after 24 hours. Strong corrosion was observed with iodine at 60C, while titanium
did not corrode after 500 hours at room temperature. other tests Indicated that
titanium reacts rapidly with both dry liquid bromine and moist bromine, although
it has high stability In aqueous solutions of bromine up to 90C. Ignition of
titanium occurs when the reaction Is highly exothermic and proceeds at a high rate,'
when the final products of the reaction are gases and when the reaction Is auto-
catalytic. The formation of TIC] and Til4 liberates large quantities of
4, TiBr4
heat. Some publications have note that arom tic nitro compounds increase the
corrosion of iron, copper, lead, aluminum and their alloys by electrolytes. This
is explained by the depolarization of 4itro compounds during the process. No data..:
are available In this respect about titanium. Tests by the authors sl~owed that
almost all nitro compounds sharply lower the corrosion rate of titanium by hydro-
chloric acid up to 60C, but at 80C this process changes and the protective action
Is observed only in the presence of o-nitrotoluene, o-nitrophenol, m-clinitroben-
zene and 1,2,4-di-nitrochlorobenzene. The concentration of nitro compounds in
ArY29j] has a marked effect on titanium corrosion at 60C. OrIg. art. has: 6

ABSTRACT: Of late glass ampoules are used for corrosion investigations of
steel; the former make it possible to carry out several ex-
periments at the same time, which fact is especially favorable
in the case of smal! sample quantities, and in the determinations
of rare metals, as well as of expensive and dangerous reagents.
In the laboratory mentioned below an apparatus was constructed
on this basis, which serves for the determinations of chemically
resistive, rare metals in hydrochloric acid. The apparatus con-
sists of a heatable steel drum with a steeltube grid into which
eight steel shells for the glass ampoules are Put. 40 n1 liquid
and two samples each were put into each ampoule; then they were
put in a sealed state into the apparatus which was rotated by
a reducing gear. After the experiment the ampoules are broken

0,005 g/m2.hour was found. Thick-walled ampoules were also
used for the determinations of nickel, copper, alu~ninium and
other metals in molten AM at 2000. The experiments with this
apparatus must be carried At taking into account all pre-

TfTLE: The Effect of Cathode Polarization of Tantalum on Its Electroconductivity
PERIODICAL: Zhurnal prikladnoy khimii, 1960, Vol 33, Nr 4, pp 850 - 854
TEXT: Cathode polarization of tantalum in hydrochloric acid is accompanied by
hydrogenation of the metal and leads to its cracking. In the experiments tantalum
plates (with about 1% of niobium), 1 mm thick and 90 mm long and with a surface of
30 - 35 cm2, were used as cathode. A graphite rod served as anode. The measurements
were carried out In an oil bath and lasted 5 - 10 minutes. Under the conditions studied
the electric resistance of tantalum in the case of cathode polarization increases in
direct proportion to the quantity of hydrogen absorbed. With an increase in the duration
of the cathode polarization of tantalum and the current density from 0.1 to 10 PVIM2, the
amount of hydrogen absorbed by tantalum increases and consequently also its electro-
resistance. With an increase in the thickness of tantalum from 1 to 5 mm the time needed
for the saturation with hydrogen increases considerably, and so does correspondingly the
electroresistance. Cracking of tantalum starts during cathode polarization, If its

PERIODICAL: Zhurnal prikladnoy khimii, v. 33, no. 12, 1960,

TEXT: The corrosion of titanium by various acids and oxidizers has
been studied by I,I. Kornilov (Ref. 1: Khim. nauka i prom. 3,6, 803
1958), MI. Eremenko (Ref. 5: Titan i ye o splavy (T;btanium and

ly little is known of the effect of chlorine on the stability of
Ti in HCl apart from some data recently published by P,J. Gegner
et al. The authors accordingly conducted a series of tes's in order
to obtain further information on this problem, thelp specific ob-
jectives being the determination of the influence of a fixed amount
of free chlorine and the effects caused by varying its ccn~;entra-
tion in the HC1 solutions The experimental procedure involves the

insertion of a Ti specimen (30 x 16 x lmm) in a glass holder; the
placing of the holder in a test tube provided with a reflux con-
denser; the addition of 150 ml of conc. HC1; and the supply of C12
gas to the solution from a cylinder. The results confirm previous
data on the high degree of Ti corrosion in HC1, especially at elev-
at'ed temperatures and acid concentrations; however, free chlorine
markedly retards this pM%pss~ Thusj no Ti is dissolved at room tem-
perazure whatever the concentration of HC1 provided the acid is
continuously saturated with free chlorine (10 ml/min). Under these
conditions Ti is also stable at the following temperatures and con-
centrations of HC1: 900 -- 5 %; 800 -- 10 %; 700 W 15 %; 600 --
20 %. As regards the influence of the concentration of free chlori-
ne on the corrosion of Ti in 20 % acid, it is shown that 01#001 g
Cl /100 ml H01 is sufficient to bring about a 100-fold decrease in
th3 rate of metal solution. This effect is annulled when the expo-
sure time is increased to 25 - 50 hours. But Ti remains in a passi-
ve ~-tate for periods of 25 and 50 hours if the initial concentra-
tioi-. of the solution is increased to 0.037 and 0.084 g C12/100 ml

of sp Zh. prikl, khimii

corrosion of many metals and their alloys. The authors infer from
the data of T.',4V. Mal'tsev et al (Ref. 10: Giredment, eb. nauch, tr.
1, 481, Metallurgizdatf 1959) that the resistance of Ti to corro-
sion by chlorinaied acid is due to the formation of an inert film
of oxides This passive layer evidently ha s a tendency towards spLln-
tering and exfoliation which is beat prevented by continuously sa-
turating the HCI with free chlorine, and it is concluded that such
a technique helps to reduce the solubility of the film in a solu-
tion of Cl possessinc a concentration of-I< 20 % and a temperature

141199 ("Tr. Kazansk. aviats. in-ta", ig6o, no. 55, 91 - 102)
TEXr: The author analyzes the possibility of utilizing the method of elas-
tic calculation of disks of arbitrary shape, widely used in plant practice, for
the calculation of disks allowing for plastic deformations and creep. The method
described in G.A. Kuzmin's article (see abstract 141108) is taken as the initial
one, in which the disk profile is replaced by sections of constant thickness. It
is suggested for elastic calculation to assume the magnitude of the modulus of
elasticity (E) to be depending on the temperature, while.the magnitude of E
modulus of plasticity" to be depending also on the magnitude of deformation at
the analyzed point. The calculation is carried out by the method of successive
approximations. The initial stress is assumed to be that which is obtained as a
result of calculating the disk as an elastic one. The modulus of plasticity is

for the section being investigated can be described by a certain curve. The
author suggests a method of plotting the network of values of the "modulus of
plasticity" considerably simplifying its determination. He presents a calcula-

ber of approximations.
