"Strength and Plasticity at Low Temperatures of Titanium Alloys
With Zirconium"
Moscow, Metallovedeni Ito 10, 1971, PP 30-33
Abstract: The mechanical properties of titanium alloys with
zirconium (up to 30%) and their stress concentration sensitivities
at 200C, -1960C, and -2690C were investigated.: The principles
of the change of strength and plasticity,as a function of Zr-
content, were experimentally determined using iodide zirconium
and.TG-110 titanium. The results are discussed by reference to
diagrams showing the mechanical properties of alloys of the
system Ti-Zr at 200C, -1960C,.and -2600C, stress-strain diagrams
of Ti-alloys with 5% Zr and 20% Zr; and their stress concentra-
tion sensitivities. The ultimate.a.trength and yield point of
the investigated alloys increase smoothly with increasing Zr-
content. By alloying Ti. with Zr, alloys of sufficient strength

"Mechanical Properties of Binary Titanium Alloys With Vanadium and Niobium.

16-19
Abstract: This study concerns the mechanical properties and stress concen-
tration sensitivity of binary Ti alloys with various contents of V and Nb
at temperatures from +20 to -269*C. Discussed are theTrinciples governing
the variation of properties and optimum alloying limius for Ti with V and
Nb for producing stronger multicomponent alloys suited for utic in the cryo-
genic technology. The strength of Ti alloys.with up to 12% V increases
4.3 times at temperatures as low as -253'C; but the alloy becomes brittle.
In Ti alloys with up to 11% Ni, the strength increases about 3.5 times and
a certain amount of plasticity is retained. :For service at temperatures as
low as -269*C Ti alloys with up to 6-7% Nb are recommended; Ti alloys with
up to 5-6% V may be used for service at temperatures as low as -253*C.

"Magnetic Properties of Rare Earth Metal and Iron Compounds of the RFe3
Moscow, Zhurnal Eksperimental'noy i Teoreticheskoy Fiziki, June 1973, pp
Abstract: Magnetic studies of the compounds DyFe3, YFe3, RoFe3, and ErFe3
including measurements of the magnetization in fields up to 53 koersteds and
of the variation,.with temperature, of the coercive force - are carried out.
The magnetic moment per RFe3 molecule and also the variation, with temperature,
of spontaneous magnetization are determined. The Curie temperature is deter-
mined by a thermodynamic method. An anomaly of the coercive force near the
magnetic compensation temperature is observed. The variation, with tempera-
ture, of the magnetic properties is due to the ferrimagnetic structure of the
compounds which is characterized by an antiparallel orientation of the mag-
netic moments of the iron.ion and rare earth ion sublattices. The Curie tem-
perature of the RFe3 compounds.increases noticeably upon an increase of the
rare earth ion spin, and this indicates that the contribution of exchange
interaction between the rare earth ions and iron ions is considerable.

Abstract: The nonlinear Droblem of the isothermal flow of a

The problem is solved on the basis of a system of nonlinear dif-
ferential equations of the bound&.ry layer type. All quantities
characterizing the gas flow are expressed in the form of functions
of pressure, which in this formulation depends only on the longi-
tudinal coordinate. An ordinary second-order nonlinear differen-
tial equation is obtained which was Integrated,numerically on the
"Mir" computer by the Kutta-Merson method with automatic selection
of the integration interval; values are given for one set of ini-
tial.parameters. The pressure distribution and velocity field
~along the tube are compared with the solution of this problem in
the linear formulation that was given in a previous paper by the
duthor. Various cases of the velocity distribution in the initial
cross section of the tube are discussed.

Abstract: It is shown that the cubic eauation for magnetization at H 5f 0 obtained
by Landau for ferromagnetics close to the, Curie point and following from the Landau
expansion is also applicable for ferrimagnetics, including ferrites. In the pe-ra-
magnetic region the susceptibility is shown to be subject to the Ne"el law and not
to the Curie-Weiss lawas in the case of fer-romagnetics. The simplest type of
ferromagnetic crystal, which can be divided into two sublattices inserted into one
another, is considered. The spins of the first sublatfice are directed to the
right and the spins of rhe second are to the left , so that the spins of atoms of
the nearest neighbors are always antiparallel. It is shown that both below and

ferrimagnetic is characterized by the fact that with a change in the field 11 and
12 the magnetizations of the first and second sublattices,by remaining antiparallel,
vary proportionally: 12 = -&I,, where E > 0 is a coefficient independent of the
field. The ferrimagnetic state with the magnetization vectors of the sublattices
ori,~nted antiparallel is thus retained upon the application of a field close to the
Curie point. -The role of the magnetic fieldIs only to induco considerably

Abstract: The influence of pressure on the galvanomagnetic effect in dysprosium
tingle crystals is measured at temperatures between 85 and 177'K. A strong de-
pendence of the pressure-induced shift of,the.critical field on temperature is
observed. A thermodynamic analysis of the experimental data for dysprosium shows
that the increase of the critical field with pressure aL 110-140*K can be explain-
ed by the growth of exchange interaction. The correlations between dHc/d and
p
dHC/dT and also between the magnetostriction and dfl,/dT found in the present
investigation indicate that the decrease of He due to cooling below 1600K, which
results in a transition to the ferromagnetic, state, occurs in dysprosium as a
result of anomalous growth of the lattice,constant c. below the paramagnetism-
helicoidal antiferromagnetism transition temperature.

10 A review of the e:-.-perimental methods for the inrestigation of elastic
scattering of protons by pro-bons and nuclei at high energica is presented in
this paper. The main results of the experinents on pp- and pd-seattering, in
the region of E > 1 bev are given. The probleTi concerrdng the verification of
dispersion relations for 01-scattering is discussed. A revim.T of the models of
NN interactions at high energies is presented.
II. The connection between the probability and qucasi-jDoteltvial descriptions
of, scattering at high energies is studied. It is shot-m that the probability
deseription of scattering may be considered as some groundn for the necessary
introduction of smooth quasi putentials to qumtum field theory.,
A review of m ethods and some results of the qua6i-potential approach
to high-energy hadron collisions'are presented.
The interaction of photons with matter is discussed. The review con-
sists of three parts:
(1) the validity oL
f quantum electrodvnamics at distan(~-'es of 10 -10 cm
(intc-ractlon of photons with electrons);
.(2) lepGon decays of vector mesons (intoraction of pbotomi -wLtl, photucri-Like
