ABSTRACT: While it is Imown (Livanov, V. A., Bukhanova, A. A., Kolachev, B. A. Vodo-
rod v titane, Metallurgizdat, 1962) that hydrogen in (of + 0) T! alloys concentrates in the
5-phase, the temperature dependence of the phatso distribution of hydrogen still bas not been
established. Accordingly, the authors investigat@--d the interaction between hydrogen and
rY- and 0-phases of (a + 0) T1 alloys ( the alloys Ti + 0. 5% Mo and Ti + 12. 590' Mo, representing
the v- and 0-phases of the Ti-Mo system in an equilibrium at 800*C, and tbe alloys Ti + 8%
Al + 2 % V and T1 + 4% Al + 6% V, representing Cae a- and 0-phases of the industrial alloy VT 6

(Ti + 6% Al +4% V) in an equilibrium at 900-925*C) at various temperatures. Hydrogen was
added in small portions to the vacuum-annealed alloy specimens, each succeeding portion
being introduced only after the equilibrium pressure due to the addition of the preceding
portion had set in. The amount of the hydrogen absorbed by the specimen was determined
according to the pressure difference in the system. Findings: in the two-phase region hydrogen
is nonuniformly distributwd between the phases. The ratio between hydrogen concentrations
in the 0- and a-phases is determined by the entropic factors and by the heats of dissolution of
hydrogen in the phases. At low temperatures in (a + 0) Ti alloys hydrogen gets concentrated
in the 0-phase, since the thermal effect of the dissolution of hydrogen in this phase (taking
polarity into account) is smaller than in the a-phase. At temp2eratures of the order of 800-900*C
hydrogen satisfactorily dissolves in the f@- and a-phases; the hydrogen concentration in the
0-phase of the Ti-Mo and Ti-Al-V systems is only 1. 3-1.4 times as high as In the a-phase. As
the temperature decreaseu hydrogen migrates from the ot-phase to the 5-phase until the hydro -
gen eoncentration ratio between these phases C/C Ct increase to several tens. The thermodyna-
mic analysis of the solutions of hydrogen in a- and 0-phases of Ti alloys applies to any two-
-phase system. Thus, hydtogen concentrations in the a- and 0-phases of (a + 0) Ti alloys are
similar at high temperatures, and it is only at sufficiently low temperatures that hydrogen
concentrates in the .'rt -follows hence that the proneness of (01 + 0) Ti alloys to hydro-
g6i'4rittleness must markadlfdev@nd on the test temperature and on. the previous heat treat-

ment. The different solubility of hydrogLn in different phases may be utilized for the internal
dc-assin- of one of the phases at the expense of the other. This method may greatly improve
the plasticity of refractory metals which, as a rule, have bee lattices and thus are particular-@
ly susccptil@le to contamination by interstitial impurities. The same principle can be utilized
for the de-assing of molten metals by means of substances which do not (or nearly do not)
interact witli these metals but have a great affinity for hydrogen. If, say, titanium is added
to molten aluminum, hydrogen from the melt will migrate to the titanium. Orig. art. has:

ABSTRACT: According to a previous hypothesis by the first three of the authors (B. A. Ko-
lachev et al. Issledovaniye titana i yego splavov, Izd-vo AN SSSR, 1963) aAe reason for the
hydrogen brittleness of a number of metals is that the hydrogen-atom atmospheres forming
at the dislocations are entrained by the latter in the presence of low straining rates, so that
the hydrogen concentration at the grain boundaries or at other obstacles at which the disloca-

tions pile up becomes sufficient for a sharp acceleration of the development and propagation of
cracks leading to fracture of the metal. Now the authors show that the hydrogen brittleness
developing in the presence of low straining rates manifests itself within a temperature range
(300-550*C) which corresponds to a specific value (10-5_10-6 c 2 a
m /see) of the diffusion coeffi-
cient- of hydrogen. In this connection, the authors investigate the effect of hydrogen on the me-
chanical properties of regular (0. 002% R2) and vacuum-annealed (0. 02 and 0. 05% H2) rods of
technically pure Ti subj ected to tensile strength tests at normal (4 mm/min) and low (0. 4 mrr/
/min) straining rates. Findings: the miniatum, elongation per unit length for Ti in the presence
of normal straining rate was recorded at 500*C (Fig. 1) while in the presence of the below-nor
normal straining rate (0.4 mm/min) the mechanical properties of the Ti with 0. 002% H 2 in-
crease up to a point with Increasing temperature whereas those of the Ti with 0. 0% H'?
steadily decrease with increasing temperature. These experiments were organized on the
assumption that the shaxp decrease in the plasticity of Ti at high temperatures is due to hydro-
gen alone. The experiments revelaed, however, that this sharp decrease in plasticity within
the temperature range of 300-5500C also occurs in technica.Uypure Ti (0. 002% H 2) -- not as
distinctly as in the Ti containing 0. 05% H9 but still distinctly enough. This sharp decrease
is apparently due to the presence of 02 and N2and resembles similar phenomena discovered

in Nb, V and other metals. In the presence of hydrogen
(0. 0570 112) the decrease in elongation at 400-500*C at
low straining rates is compounded by tlio hydrogen
brittleness due to the transport of hydrogen toward the
grain boundaries. The effact of hydrogen on the pro-
perLies of titanium within this temperature range is
sinidlar to the effect of strain aging. Orig. art. has:

ABSTRACT: *Hydrogen-induced embrittlement of VT3-1 and other a + 0 titanium alloys
Idepends not only on the hydrogen content, but to a considerable extent
ion the cpntent of other impurities, heat treatmat, grain size and Vie
@type and conditions of deformation. To determine the effect of the
:various factors, several series of specimens of modified (with increased
*Al, Fe and Si content) VT3-1 [U.S. Ti 155A) titanium alloy with a hydro-,
gen content of up to 0.1 wt.% were annealed at 800C and slowly cooled, orj

the alloy annealed and slowly cooled, a hydrogen content of up to 0.1Z
had no significant effect an the ductility. of the alloy at a deformation
as low as 0.4 mm/min, while in the as-quenched-alloy deformed at the
same rate, a substantial decrease in the reduction ef area occuri-ed at a hydrogm
'content of 0.003% R . However, at a strain rate of 4 mm/min, no noticeable
1change in the reduchon of area was observed in as-quenched alloys con-
.taining up to 0.05% H.. The brittleness of as-quenched alloy increased,
;with increasing annealing temperature, since this decreased the amount
!of residual a-phase and increased the amount of the a-phase. An
especially strong effect of hydrogen was observed in aged VT3-1 alloy.
IShort (0.5 hr) aging at 550C significantly increased the tensile and
iyield strengths of the alloy containing 0.03 and 0.05% hydrogen and
.sharply decreased the elongation and reduction of area. The alloy
.strength decreased and ductility increased with increasing aging time
from 0.5 to 3 hrp but changed only slightly@%!Lth stil.1 Long-ar aging.

TEXT: The effect of vulcanization on the strength of branched elastomers
able to bind sulfur to the double bond of vinyl side groups is studied.
Rubbers on the basio ol' CMS (sYB) , CV,6M, (SKBM) , and CKA (SKD) poly-
butadiene rubbers containing vulcanization groups and 10 parts lay volume
of lampblack were calendered on polycaprolactam (Perfiol IrK-4 (PY-4)) and
hydrate cellulose filma. Vulcanization was conducted at 1340C and
--'0.85 kg/cm 2 on the drum vulcanizer "Berstorf". 'When -the molecules
contain vinyl side groups, sulfur and also oxygen may add and influence
the adhesion of elastomers, which was determined according to r0GT 6766-53
(GosT 6768-53). Double bonds do not chanee the dependence of exfoliation

1.1 kg/cm,-that for SKBM is v1O min, 1.0 ke/cm, since SKB contains a
number of branches. The change in exfoliation character for SRB and SKMM,
is due to stronger adhesion with constant cohesion. The difference in
time is explained by a higher rate of solidification of the adhesive bond
and somewhat lower cohesional force of SKB. The dependence curve of the
adhesion of SKB and SKBY, rubber on the structuration degree (molecular
weight 11, of the chain link), after vulcanization has a flatter drop than
the corresponding curve for butyl rubber, butadiene styrene and butadiene
acrylonitrile elastomer3. In the vulcanization of butadiene elastomers,
sulfur attaches to the double bonds of the principal and vinyl side
chains, forming numeroun sulfurous Eroups with intramolecular interaction,
and also large, hardl.,f mobile, cyclic sections. The diffusion rate
therefore decreases at a Mc higher than that of elastomers with inter-
molecular sulfur addition only. The structuration degree depends on the
number of links bound in the 1-2 position of elastomers. An increase in
the number of links in the 1-2 position reduces the adhesive szorenCth at
higher Mc, increases the double bon-is in the side groups and the 14A c max$
and decelerates the decrease in adhesive strength after maximum structura-
tion. There are 4 figures.

TEXT: The authors studied (1) the vulcanization of CKS -35-P (SKB-35r)
sodiLm butadiene rubber with tetramethyl thiuram disulfide alone, and
(2) the vulcanization of polychloroprene rubber in the additional
presence of oxides of multivalent, metals. The maximum strength of the
adhesion bond was reached much earlier than with sulfur vulcanization.
Examination of the structuration rate of the rubbers showed that the
degree of structuration of the thiuram vulchnizate (I) in the first
20 min was higher than-that of the sulfur vulcanizate (II). After long-
time vulcanization it remained unchanged with I and incrQased with II.

Effect of the structuration of ... 3110/B144
The mEximum strength of the adhesion bond of I is lower since I diffuses
less readily than II (II - 1050 g/cm; I - 4ao g/cm). The maximum
degree of structuration, after which the strength of the adhesion bond
decreases, is; 14 c max -@ 50,000 for II, and Mc max -_ 65,000 for I. This
confirms the effect of the macromolecular bonds formed on vulcanization.
The -C-C- and C-S-C bonds of I are more rigid-than the -C-Sn-C- bonds of
Ii. The strength of bonds between rubber and fiber-forming polymers is
thus reduced, and optimum adhesion is shifted toward a lowe= degree of
structuration. Furthermore, the authors studied the effect of the-
vulcanization of rubber mixtures on the basis of polychloroprene rubber
(nairit) with zinc and magnesium oxide on the change in strength of
adhesion bonds between rubbers and fiber-forming polymers. The adhesion
bond of polychloroprene elastomers with polyoaprolactam and hydrate
cellulose showed no change in the dependence of the strength of adhesion
bonds on the vulcanization time by metal oxides. Ifere,too, the optimum
occurred at a shorter vulcanization time than with II. Since the
adhesion strength :ceached a maximum at Mc max ' 7-7500 and decreased

subsequently, the type of vulcanization was found to have no effect with

ABSTRACT: The Gd3* ions introduced in artificially grown CaF2 fluorite crystals
are in fields which are partially of cubit: and partially of tetragonal symmetr@. In
both cases the compensation of the excess charge of Gd3* substituting the Ca * ions
is carried otit by an additional fluorine ion. The present article gives an estimate
by means of the electron paramagnetic :resonance method of the absolute concen-
tration of Gd34 ions embedded in CaF and located in fields of cubic and tetragonal
symmetry as a function of the overalf6d* concentration within the crystal.
Crystals with admixtures of Gd 0 were grown in vacuum by Bridgeman's method
in graphite crucibles at a rate oi 19 mm/hr. The author presents the basic theory
and the experimental results which show that with an accuracy not worse than 10-12%

the electron paramagnetic resonance can be used to determine the concentration
of the embedded paramagnetic centers. The accuracy of the method depends on
such radiospectros cope parameters as the stability of the generator, the pass bands
of the amplification chain, and the inhomogeneity of the alternating magnetic field.
In case more than one symmetry of the crystalline field is possible, the ratio of
the ions found in the fields of varying symmetry depends on the overall concen-
tration of the embedded admixture. This pattern was observed even on a cubic
aqueous crystal in which in the presence of tetragonal and rhombic symmetries of
the crystalline field, the ratio of these symmetries alsb depends on the concen-
tration of the embedded paramagnetic centers and the conditions of growth. The

by the solution-In-melt mJ_h3d. A study of the angular dependence 5r the orienta-
tion H I z showed that within the accuracy of the experimental errorp gX - g - &L
Because of the imperfection of the crystals, the hyperfine structure of the Mi-43 and
Nd145 lines in the principal orientations did not show up distinctly; therefore, the
measurements were made in an orientation such that N was parallel to the bisector of
the angle between zi and z2 and thus formed an angle of 22-50 with both zj and Z2.
The spectrum was described by means of the usual spin Hamiltonian of axial symmetryo
The follow-Ing Hamiltonian parameters were found:

ABSTMCT: The purpose of the investigation was to determine the behavior of iron-
group elements in crystals in which the ligand atoms form a cube or a tetrahedron
rather than the deformed octahedron characteristic of most crystals used for EPR
research. To this en6, CaF2 crystals doped with V and Cr were grown under controlledi
conditions and their FM spectra studied. No EPR spectra could be produced in the
CaF2, even at 4.2K, unless a small amourxt of FbF2 (0.5 - 1.5 wt.%) was added. The
optimum was 0.6 wt.%. A type-I EPR spectrum of vanadium was then observed at 77K.
When the CaF2 crystal was prepared in a fluoriding atmosphere (by burning teflon in
the furnace), a type-11 EPR spectrum of vanadium was observed at 77K. The same
treatment was necessaxy to grow cryutals with observable EPR spectrum of chromium.
A formal analysis of the EPR spectra on the basis of the spin Hamiltonian is pre-
sented. The parameters of the spin Hami.1tonians are determined. The type-1 EPR

results show that,the ions V++ and Cr+++ are in the electric field of trigonal SYM-
metry and those of V.. in a fieUI of cubic symmetry, which cannot be regarded as
consisting of strong cubic and weak trigonal components. The trigonal component is
related to the Jahn-Teller effect.. The authors thank S. A. AlItshuler and A. M.

ABSTRACT: The author considers the system@Lz- - f(z,t), where f(z,t) are
dt
discontinuous, in general not periodic functions. By defining a
linear approximation as in the papers of M.A.Ayzerman and P.R.
Ganbmakher CRef 1,2_7 it is possible to investigate the
stability of the solutions. The author obtains criteria of
stability which generalize the well-known criteria of K.P. Per-
sidskiy, O.Ferron, and I.G.Malkin to the case of discontinuous
right sides. The author introduces a generalized Lyapunov
function and proves that such a function exists for the system
of linear approximation. Five extensive theorems are formulated.
There are 8 references, 6 of 7thich are Soviet, and 2 German.
