ABSTRACT: Due to the fact that the permissible cut-Ling speed and
stability of the standard P-18 Soviet high speed steel
are low, experiments have been carried out the aim of
which was to find new composition of high speed steels.
Medium (11.5%) and low.(3,58%) tungsten steels with about
5.5% Co were used in the experiments; the compositions
of the three experimental steels are entered in Table 1.
p.48. The blanks are easy to forge and to machine; the
fo]E~'ng was effected using the same regime as that used
for kstandard Soviet high speed steel P-18. The heat
treatment of the ingots consisted of slow hehting to
900 C, holding at that temperature for three',hours,
cooling to 740OG and holding for t8n hours, followed by
slow cooling in the furnace to 500 C and furtl~er cooling
in air. During nnnealing, the blanks were pack6d into

with cobalt have a strong tendency to become decarbur~ised.
The heat treatment regimes of the cutting tools and of,.t he
experimental steels are entered in Table 2. Table 3
contains data on the influence of the hardening
temBerature and the effect of repetitive tempering at
500 C on the hardness of the experimental steels. It was
found that treble tempering after hardening ensures a
high stable hardness; the obtained results for one of the
steels (containing 0.97% Vb) contradicts literary data
according to which Nb reduces the hardness of high speed
steels. The results of measuring the quantity of
austenite in theo experimental steels after hardening and
tempering at 560 C are entered in the graphs, Figs.1-4.
For det-ermining the red shortness, the stsels were
subjected three times to annealing at 600 C for one hour
and after each of these cycles the hardness was measured;
the results are graphed in Figs-5-7.. As can be seen
froW the results graphed in Fig.8, sub-zero treatment at
-78 C brings about a considerable reduction of the quantity
0
of the residual austenite and a sharp increase in the
Card 2/4 hardness. Table 4 S;Lves the bending strength of the

experimental steels after various heat treatment regimes.
Table 5 gives the chemical composition of the carbide
phase of these steels, whilst Table 6 gives the
hardness values after various heat treatment regimes.
The cutting properties of these steels for discontinuous
machining were investigated for a machining speed of
6 m/min, a feed rate of 0.6 mm/rev and a depth of out
of 1 mm. The graph, Fig 9, shows a comparison of the
service life of the expe;imental steels (in the case
of machining a specific high temperature steel) treated
according to the regimes enumerated in Table 6. Under
similar conditions, the service life of cutting tools
made of the steel P-18 averaged 17 mins as compared to a
nazimum of about 75 mins in the case of the experimental
steels, The results have shown that cutting tools madS
of one of the tested steels (harden,-Q a! 01230 and 1250 C
followed by tempe-king three times at 560 C) had a service
lire two to three times as MESh as cuttin2; tools made of
the standard Soviet high speed steel P-18, which proves
that cobalt containing low and DiediuT-,a tunGsten high

TEXT: A. S. Davydov and G. F. Filippov calculated the collective energy
levels of axisymmotric even-even nuclei, taking the interaction between
rotational and vibrational states into account, and determined the rota-
tional levels and the tranai*ion probabilities between them for non-axial
nuclei, without considering the vibration-rotation coupling. These investi-t/
gations are complemented by the present paper which describes an investi-
gition of the vibrational-rotational collective excitations for non-.waxial
even-even nuclei. The vibration energy is assumed to be much higher with
respect to the non-axiality parameter y than the energy of collective ro-
tations and vibrations with respect fo P, so that y may be considered to
be constant. An expression (1) for the nuclear energy is-formulated accord-
-I- the generalized Bohr model. From (1) the author proceeds to the

Rotational Energy and Moments of Inertia of Nonaxial Nuclei

Vol- 38, No. 4, PP- 1311 - 1315
TEXT: A~ S, Davvdo.v, G. F. Filippov, and V. S. Rostovski developed a
theory of the rotational states of nonaxial nuclei (Refs. 1,2). They
showed that the ratios of the energies of all rotational levels to the
energy of the first excited spin-2 level can be uniquely determined if
the corresponding ratios for the second excited spin-2 level are known
from the experiment. It was further found that the relative probabilities
of electric quadrupole transitions between rotational levels may also be
determined from these ratios. These results were obtained on the assum.p-
tions that a) the inner state of the nucleus does not change during its X
rotation (adiabatic approximation), and b) the main moments of inertia
of the nucleus can be expressed by the parameters A and 1:

dynamic nuclear model. The authors therefore described this approxima-
tion as hydrodynamic. The authors now investigate the question as to
the manner in which these results change if the simplifying assumptions
are abandoned. The rotational states of nonaxial nuclei with arbitrary
(three) main moments of inertia are investigated in adiabatic approxima-
tion. It is shown that in general the rotational energy ratio may be ex-
pressed by two parameters: byf, the energy ratio of two spin-2 levels,
and by 1, a parameter depending on the character of the collective mo-
tions causing nuclear rotation; E (2)> 1, aj~ a /E3(2).
~ = 2(2)/El B2 3 1
In the following, the energies of all rotational states are expressed
by the dimensionless E: E = E/Ej(2). Thus, the following relations hold
for the spin-2 and spin-3 states as, e.g., E(3) - 1 + , F-10) - 4 + f,
E; 2(5) = 1 + 4 t. The energies of other rotational levels cannot be given
as functions of but they are functions of f and 1. For the

ABSTRACT: The author shows tbat,the reported observation of an additional ultrasonic
signal (H. Kroger et al.j, P*s-. Rev. Lett. v. ll,, 246p 1963) following amplification
of 107 cps transverse.oscillations by carrierdrift in a CdS crystal can be inter-
preted as isome diffraction effecto caused by thi anisotropy of the amplification co-
efficient. This phenomenon is,similar to birefringencep where a wave with anomalous-
-ly low front-propagation velocity:likewise exists; in this casey however, the aniso-
tropy of importance Is not that ofthe real but of the imaginary part of the 'wave
number. A concrete calculation for thesimplest case of a cubic crystalp assuming
that the amplification is at the expense of the deformation potential., shows that,
under the assumptions made., the anomalous wave can have a larger ampLitude than the
ordinary wave. The velocity of the anomalous wave observed experimentally agrees
qualitatively with the presented theory. It is noted in conclusion that a perfectly
analogous phenomenon) the reception of two signals, will occur also if the damping

the.existence of two wavesp ordinary and anomalous, for the case when the imaginary
part of the wave vector is anisotropicp both when the waves are amplified and when

trary type propagate in a medium in which the properties that,govern the propagation
of waves of this type.exhibit anisotropy. Author is grateful to Yu. L. Gaz M.

ABSURACT: The author analyzed the effects produced in a piezoelectric crystal uni-
formly illuminated-by a linearly po 2
Japi ed laser beam. First, electrostriction gives
riseto a deformation. Then the piezoelectric projertieg lead to polarization of the
crystal.. An estimte shows that at a power W - 10 v/ce, a potential difference of
100 v will appear on a layer 1 cm vida-.-An inviastigation of the potential differ-
ence induced by light in piezoelectric crystals can identify experimentally the de-
Jormations actually produced by the light field. 7he intensity LO of the constant
electr1c fleld may become particularly large when the laser beam is focused or self-
focused in the piezoelectric crystal. When W a 103.2 w/cm2, correspo li~ toloaali

conditions this ionization mechanism may be -strongw than multiphoton ionization un-
'der the influence of light. Since the free -electrons produced when the atoms are
ionized weaken the field IP, the crystal may at first glace not become damaged during
.the time of action of the light pulse, even at so high a beam intensity. However,
for an effective compensation of IP, the concentration -of the electrons should amount
to n - 203,4 cm73. At such conduction- electron concentrations, if their mobility is
not too high, the light can be completely absorbed over -a distance smaller than I cm.
Then simple estimates Ahow that'heating during, the Ume of- wt1on of the light pulse
amounts to thousands -of degrees, and will de e the crystal. Upon focusing or self-
focusing of the light beam, an electric field that is constant in time will appear in
crystals with Aimmetry centers because of the inhomogeneity of the deformation over
the cross section of the-beam or of the foe al spot. An estimate shows that in this
case 9D - 103 v/ca when W ~_ -1012 V/CM2 and that in very narrow self-focused beams in
a non-piezoelectric crystal the intensity of the constant electric field can exert a
most appreciable influence on the propertief of the nedium. Orig. aft. has: 6 for-

ABSTRACT: 7he author discusses the self-focusing of !elliptically polarized light
(and of circularly-polarized light as a particular case), and the differences in the
self- focusing -thresholds for linear, circular, and elliptical polarization. 7his
question has a direct bearing on leaser-beam stratification in the case of elliptic
polarization of light in liquids, as well as in solids, where electrostriction is
the stronger self-focusing-mechanism. It is shown that if the polarization ellipse
is prolate (ratio of axes > %/2-) only a self- focusing'channel vith linear polarizatior
of the'light can be produced in the liquid. Two geometrically independent channels
with linear polarization are formed in the case of circular polarizattion for which
the light intensity is smaller than threshold for formation of a circular polariza-
self-focusing channel, but higher than that for linear'liolarizatich.- --Linear-
polarization channels can likewise be'-produced if the intensity~-ot-tiii-iifr-cuiitriy-

nel. It is thus demonstrated that in many cases ellipticaLly polarized light is more!
likely to form channels with linear polarization. Although in solids the predominant,
self-focusing mechanism is electrostriction..' nevertheless the Kerr effect can still
cause striations in a laser beam, but in this case the polarization in the channels
will be elliptical and not linear. Orig. art. has: 3 foivmlas. [023

analogy between the acoustic behavior of nradla with microscopic inhomo-

the corresponding calculation for an emulsion, with certain substitution
of the quantities characterizing the components, The proposed theory
has no free parameters and all the quantities Involved in the calcula-

theory agrees well with experiment and makes it possible to interpret
in natural fashion several phenomena hitherto unexplained (the experi-

ABSTRACT: The experimental data on anomalous absorption and dispersio
of sonic, shear, and-electromagnetic waves in highly viscous liquids
indicate that the relaxation theorj~of wavee'propagation is not appli
cable to these liquids. It is assumed thhat In a wave, tne ordered
regions undergo a rearrangement,.and the equilibrium number of holes
is changed with respect to the second disordered component. The
disturbed equilibrium with respect to the number of surplus holes is
't of
restored by the diffusion between the components. The phase shif
this process in respect to the incident wave results in anomalous
absorption and dispersion. It Is assumed that the static displace-
ment viscosity of the medium is due to the mechanism of the Maxwellian

relation. In the analysis of. the electromagnetic waves it is
assumed that the mechanism related to microinhomogeneity of the
medium is superimposed on the Debye relaxation mechanism. No free
parameters have been used in the calculations. Specific calculations
of the wave velocity and absorption have been carried out for a
number of highly viscous liquids (glycerine, butandiol, hexatriol,
2-methylpenthadiol-2-4). The ordered inclusions have been assumed
to be spherical In shape. Good agreement between theory and experi-
mental data has been obtained for these liquids throughout the dis-
persion region. The characteristic temperature for appearance of
ordered regions has been indicated. Certain possible ways have been
indicated for determining the sizes of ordered regions at various
temperatures. According to a preliminary estimation, six glycerine
molecules fit into the linear dimension of the ordered region at
22C. The authors thank V P B zhnichkina S-Or preparing a number of

Title Concerning the Problem of the Faraday Effect in Semiconductors
Orig Pub Zh- tekh- fiziki, 1956, 26, No 5. 938-940
Abstract When electromagnetic waves pass througba semidonductor pla-
ced in a magnetic field (H), the plane of polarization is
rotated. The angle of rotation & , called the Faraday an-
gle, is 0 = VlH, where 1 is the thickness of the specimen
and V is the Verdet constant.V
Here R is the R-11 constant, r is the electric conductivity,
and --q the index of refraction. This formula takes into ac-
count only the rotation of the plane of polarization by
free carriers. The rotation of the lattice itself is appa-

ABSTRACT: In 1957 the SouthernDivision of ORGRDS tested the thermal
.insulation of a high-pressure sot in the Pridneprovsk
regional pourer station and of a super-high-pressure set
in the Cherepetsk Power Station. Measurements were made
of the thermal losses throurgh the insulation and of the
distribution of the losses-between sets and equipment.
Thermal losses from particular parts of the sets are
tabulated. In the high-pressure unit, 1.2G% of the total
heatvvas passinG through the insulation, and in the super-
high-pressure sets l."o. Not all this heat is wasted

About 80/%, of the losses occur In the boiler-house. The
losses are greater in the super-high-pressure set because
the temperature is higher and -the pipinF, is lonGer.

Design of Round-Finishing Roll Pass
Metallurg, 1959,,'-. J~Nr 10, pp 26-27 (USSR)
The authors believe that the maximum wear which
occurs in the part of the roll pass, under an angle
of 450 to the horizontal, Is caused by maximum re-
duction in this part of the roll pass. In order to
make the roll pass approach a round shape after wear,
the authors suggest designing a roll pass with a
minimum diameter under a 1150'angle in relation to
the horizontal. For the design of a round-finishing
roll pass, horizontal and vertical axes AD and BC
see Fig. 2)and lines Ne and Mk under an angle of
to AD and BC are drawn. Arches with radius .
W
R = R +x f orming the roll pass profile are drawn
as foTMws: De from point 01, MA from point 02,
AN from point 0 33 and DK from point 04. Assuming

where Am, minus tolerance, d = nominal di-
ameter of the circle. Coordinates x and y of points
01P 021 033 and 04 are equal. They are determined
on the assumption that Ne and DIK equal minimum
diameter of the circle in the hot state. From Fig. 2,
