To obtain the higgh velocities for the collisions, explosive mate-

Structural Stability of Ni-W and Ni-Mo Composites"

Abstract: The problem of creating structurally stable composites for the
Ni-W and Ni-Mo system was examined. By alloying the nickel matrix with
tungsten up to the maximum saturation of the nickel solid solution, rein-
forced tungsten fibers were obtained in which the fibers did not dissolve at
1000-1200*C. At these temperatures the Ni-I-Io composite was not so stable
because an intermetallic compound is formed at.the fiber-matrix interface

Translation: The ax-ticle contains a report on-the results of calculations
of-the change in parameters of shock waves~formed bydetonation of an ex-
plosive charge as these waves propagate in three-component ceramals. The
alloys were compositions made up of tungsten carbides -- chiefly WC -- and
softer metal -- cobalt. Two cases ofinteraction are calculated: propa-
gation.in a semi-infinite layerof material of a.plane* shock wave formed by
detonation of a charge located on the surface of the material, and the ac-
tion of a sliding detcnation wave on a material surface. The system of
equations used in the calculations contains-equations,of conservation of
mass- and.momentum for the detonation-and shock.waves, end equations of
state:for the ceramals and the prbducts~of-the explosion. The results of
the calculations are given in tables and raphs.

To carry vat the calculations experimentally by the methcd of reflec-
tion, the adiabatic shock curve was determined for NrK-8 alloy in specimens
12 mm in diameter and 3-4 mm thick. The dimensions of the particles of
hard carbide Dhase and softer cementing cobalt phase were of the order of
0.5-10 V. The resultant adiabatic shock curve in the form of a linear re-
between the wave velocity D and the mass velocityu is given as
D= 4.52+ 2.28u km/s, and is valid over the pressure range of approximately
1010-6-1010 N/M2 b a
A method is proposed:for calculating the adia atic
shock curves of three-component systems which utilizes knouledge of the
adiabatic shock curves of each individual component. The adiabatic shock
curve calculated for VK-8 alloy coincides satisfactorily with the experi-
mental curve. The results of calculations of the adiabatic shock waves

for WC, VK-11, VK-15, V,-20, VK-25 and VK-30 are given. it is pointed
out that the results of experiments on x-ray analysis of the study speci-

Translation: The aut'nors consider motion of a thin-walled metal tube when
an explosive in contact with the tube is detonated in.tvo cases: 1) the
explosive charge is located on the outer surface of the tube around its cir-
cumference, has a finite thickness and borders with a vacuum, and 2) the
charge is located inside the tube and fills~it solidly throughout the
entire cross section. It is assumed that in both cases the detonation
front is flat, the detonation wave satisfies the Chapman-Jouguet-rule,
azid the products of the explosion comprise a polytropic thermally non-
conductive gas. The motion of the products of the explosion is analyzed
in the cylindrical coordinau
te system which is tied to:the detonation

of the tube was considered compressible in calculating its motion. A system
of transcendental equations is derived whose solution defines the maxiimun

Abstract: In phenomena for which the deviations of the curren't carrier concen-
trations from equilibrium are observed, the- capture processes in the traps can
'play a significant role, If the formation of nonequilibrium current carriers
is the result of internal ionization in. the semiconductor as a result of an
external electric field, it is possible to 'expect.that the capture of the car-
riers by deep traps leads to characteristic features of,.the volt-anpere charac-
teristics of the samples. A study was. mhde of the behavior of setaiinsulatinz.
GaAs: Cu in strong electric fields at T = 77* K. The
parallel effect of mo
mechanisras - generation of nonequilibrium current carriers as a result of a
strong field mechanism and capture of thetfi by deep traps leads to switching
of the sample to the state with high currents. A study was made of the effect
of infrared radiation from the photocurrent extinpuishing region on the dark

"Structure of the Reaction Products of Amidoesters of Alkylphosphonic
Acids With Phosphorus Pentachloride"
Leningrad, Zhurnal Obshchey Khimi-1, Vol 43(105), No 2. Feb 73, pp 267-274
Abstract: Reactions of phosphorus pentachloride with the amides of ethyl
and aryl esters of methyl-, chloromethyl-, dichloromethyl-, and trichloro-
methyl phosphoric acid were studied in an attempt to determine under what
conditions isometic products could be obtained. Analyzing the products
by the IR, NMR31P. and NMR 1H spectroscopical methods, it was shown that
depending on the alkyl radical attached to the phosphorus atom, the
reaction products could either be trichlorophosphazoalkylchloro- and
alkylaroxyphosphonyls, or their isomers -- alk-yldichl6ro- and alkyl-
aroxychlorophosphazodichlorophosphonyis or their mixture.

"Acidolysis of Reaction Products of Amidoesters of Alkylphosphonic Acids
With Phosphorus Pentachloride".
Leningrad, Zhurnal Obshchey Khimii, Vol 43'(105), No 4, Apr 73, pp 747-750
Abstract: Alky1dichlorophosphazo- and alkylaroxychlorophosphazodichloro-
phosphonyls react with anhydrous formic acid yielding alkyldichloropbas-
phazo- and alkylaroxyclil.orophosphazochloroxyphosphonyls. Acidolysis of
trichlorophosphazotricliloromethylchlorophosphonyl yields the ch lo roanhyd ride
of N-dichlorophosphonylamidotrichloromethylphosphonic acid. The structures
of the products were proposed on the basis of NMR31p
and IR spectroscopic
data. All of these products are dense liquids soluble in benzene, dioxane,
and acetone, insoluble in petroleum ether.

Translation: A study was made of the insecticidal activity of esters with
the formula ROP-(X)(NHCONHR')2 (1) (X = 0 or S; R alkyl, aryl; R' = Ph,
C6H4SCI'-r, a-pyridyl) for rice weevils, housefly larvae and imago and
greenbugs. The I containing the SCN-group have the highest insecticidal
activity, and among them the activity rises on going from the methyl to
the propyl and isopropyl radicals.

has been shown by neans of IR spectra that the lig-ards are coordinated vith the

ability of the ligands depends on the stfostituents at P=O and C=O. OR-Gubsti-
tuted ligands at P=O and C=O give less stable complexes than the R-substituted
ones (R = alkyl or aryl grouns).
