TITLE The Radiation Method of Computing the Intensity of Wave Fronts.
PERIODICAL Dokl.Akad.Nauk, 110, fase.3, 355-357 (1956)
Issued: 12 / 197-
The development of dynamic seismology requires the computation of the inten-
sity of the longitudinal and transversal waves in inhomogeneous media and on
the occasion of the reflection of waves by a curvilinear boundary. Such compu-
tations can be carried out if their relations holding good for the characte-
ristic varieties (of the equations describing the wave processes) are known.
An important part of this method is based on the assumption that the in-
homogeneous medium "in the small" may be considered to be homogeneous and the
curved wave front as plane.
Let it be assumed that t - T(XPYIZ) is the equation of the wave front at the
moment t. Frequently solutions of the wave equations or of equations of the
elasticity theory must be investigated which are characterized by discon-
tinuities of one or the other type.
The wave process is to be described by a scalar or vectorial function
u(x,y,z,t). Nothing is assumed as to the type of the discontinuities and it
holds that u uo(Xjy,z) f 0 (t-T) + U 1(xly,z) f,(t--r) + 0(f2(t-T)) with

function u01 is described as intensity of the wave front.
The above expression is now inserted into the wave equation with variable
velocity u -(1/a2(Xtypz)) u tt - 0. Thus, the thoroughly examined equations
I '~ P r 12 1/021 2 (V -r, Vu 0) + U0 A T - 0 are obtained. Analogous equa-
tions are given for the equations of the elasticity theory of an inhomogeneous
medium. Next, the field of the extrema of the integrals
ds/a with a + 2,~,)/q'anci ~ ds/b with b are examined. "ach

extremum of these integrals is characterized by tw: parameters each. In the
plane case the formulae are analogous, but the extrema of the integrals are
each characterized by only one parameter. Analogous formulae can be derived on
the basis of energetic formulae.
The front of the longitudinal and transversal waves can easily be determined
in homogeneous and inhomogeneous media on the basis of the F M I principle.

TITLE: Pressing and Sintering of Boride Powders
PERIODICAL: Metallovedeniye i termiche3kaya obrabotka metallov,
1960) Nr 1. pp 31-35 (USSR)
ABSTRACT: The first investigation of the processes of pressing
powders of various compositions was carried out in
earlier work (Samsonov, 0. V., Neshpor, V. S.s D*A.N*
SSSR, Vol 104, 1955). Later on 0. A. Meerson de-
veloped a theory of sintering for plastic metals.
In this work the authors investigate the pressing
and sintering of (1) titanium and chromium boride
powders, and (2) titanium and chromium bortde alloys
(ratio of molar concentration TiB :CrB = 4:1). The
initial titanium and boride powde;s we;e prepared
by the thermal-vacuum method, and double titanium-

Pressing: The method of investigating the process of
pressing consists In studying the effect of holding
under pressure on density of compressed briquettes,
measuring the elastic aftereffect, and studying'
the effect on density of intermediate grating of com-
pressed briquettes. None of the tested plasticizers
markedly improved the pressibility of briquettes,
although briquette strength was at a maximum when
using V=Cl solution. Fig. 1 shows the results Of
pressing depending on compacting pressure. The data
show that TiB2 is endowed with the best pres�ibility.

of the investigated materials is of major importance
since the character of the relationship of aftereffect
and pressure is connected with high brittleness and
nonplasticity of borides. Sintering: In order to
observe sintering conditions, the briquettes were com-
pacted under a pressure of 3 ton/CML~ and sintered in a
vacuum (0-1 mm Hg) in a retort furnace with a graphite
heater. To determine the optimum sintering tempera-
ture the specimens were sintered within the 1,700-
2,4000 C range for 1 hr. It was found that the sin-
tering process occurs in two stages: (1) minor density
Increase at maximum temperatures up to 2,100-2,2000 C;
and (2) intensive density increase above these tempera-
tures. TiB 2 boride and solid solution (Ti,cr)B 2 ware
held at 2,300 0 C while CrBO was held at 2,0000 C:
The maximum density was obtained at a holding time of
120 min. As a result, the process of compacting boride
briquettes in sintering consists in drawing particles

of sintering at which the forces of surface tension

predominate over the strength of the particles which
became plastic. The investigation shows the pos5i-
bility of pressing and sintering separately, instead
of using the complex and expensive method of hot
pressing. There are 3 figures; 3 tables; and 12 ref-

TITLE: Some problems of ultrasonic machining hard-melting
ceramic materials
PERIODICAL: Vestnik mashinostroyeniya 1/7 no. 3, 1961, 63-66
TEXT: Cast heat resisting alloys as well as alloys based on car-
bides and bonded with nickel or chrome work in temperatures up
to 10000. The alloys based on carbides, nitrides, borons and si-
licides of rare metals are considered as the most promising by
K.I. Portnoy and G.V. Samsonov (Ref. 2: Boronnye splavy, VINITI,
1960). They posses high creep resistance and hardness as well as
thermal stability, but it is impossible to machine them by usual
methods. Their grinding has a low efficiency, whereas anode ma-
chining produces cracks. Ultrasonic machining is, therefore, the
most suitable. The main criteria of the former method are the

wear of the tool and material. The accuracy of the machined pro-
file is reduced when the wear of tool is significant. The authors
determined experimentally the coefficient K which is the ratio of
wear of material to that of the tool. Specimens were prepared
from powders of hard melting alloys of sufficient purity and ho-
mogeneity. Specimens were obtained by hot pressing in a labora-
tory lever press, and their porosity varied between 0 to 255' in
order to study the effect of porosity on ultrasonic machining.
After shot blasting, specimens were weighed to determine their
density. The ultrasonic maching was carried out on a cast iron
disc and using boron carbide suspension in kerosene. To assess
the wear of tool and the value of coefficient K, the concentrator
was made according to the exponential law of reduction. Balls from
bearings were used as a tool, and their wear proved to be mini-
mum compared -to other materials. The spherical foriiri of the ball
allowed most accurate data to be obtained. The machined blind
holes were measured with a dial indicator. The amplitude of swing
of the tool vibrations was 0.10-0.11 mm, and the frequency was

18 - 20 Kc. The concentration of abrasive was 40-60%, which is
tile optimum, and its grain size - no. 150. The static load on the
tool reached 400 g. The hardness of the material as well as its
brittleness characterize its ability to plastic deformation. It
is possible to assume that less ultrasonic energy is required for
plastic deformation of harder materials and, therefore, a greater
part of the power will be directed to breaking (cutting). Higher
porosity of ceramics reduces the cross section of contacts be-
tween the particles, which affects the machinability. Comparison
of data does not permit a relationship to be established between
K and the microhardness of the material. It was noticed that
specimens of the same material, but of different density possess
unequal coefficients K. Alloys of W 2B, MoSi 2' ZrC as well aB the
heat resisting alloy BS-1 with a relative density from 70 to 100%
were investigated. The data obtained show that higher porosity
improves the ultrasonic machinability, It should be noted that
the machinability of ceramics is 5-10 times greater than that of
carbides. There are 1 figure, 4 tables and 6 references: 5 Soviet-

ABSTRACT: The vibrations and stability of a composite triple-layered conical shell were
investigated. The shell consisted of two isotropic coaxial smooth layers rigidly
joined at contact points formed by a corrugated middle layer. An ideal incompressible
was flowing in th~L_channela formed by the corrugation cr:Lmps and
fluid of density P,__
the external ahelle. The general rate of flow in the middle layer was constant. The
analysis employs it coordinate system based upon the median surface of the middle layer-
Coordinate lines ure the lines of principle curvature of this surface, and the origin
is at the apex of the cone. The following variables and constants are defined: hip

sheet thickness of the middle layer, respectively; El, E 2, and E are the respective
moduli of elasticity; Y.: and 0 are linear and angular coordinates; a is the angle
between the generatrix and the axis of "the cone; x0 is the distance along the
g,eneratrix frou the ap(m of the cone to the lesser face; L is the length of the cone
along the generatrix; t is the length of the corrugated wave; U 0 is the velocity of
the fluid on the larger face; u, v, and w are components of the translation vector;
R0is the radius of tho section of the coordinate surface at the larger face. An
equivalent orthotropio smooth shell of thickness h 3 is substituted for the corrugated
layer according to the method of L. Ys. Andreyev (Raschet gofrirovannykh membran kak
anizotropra.vkh plastin, Inzh. ob. t. 21, M., Izd-vo AN SSSR, 1955). Elasticity
conditions for the coo:rdinato surface are given by S. A. Ambartsum,,ran (Tooriya
