The methods of X-ray and metallographical analysis were used tc
Investigate the effect of temperature of preparing a single-phase solid sclution
of TaC-WC on the duration of the incubation period and the dispersity of phase-~~
aft?r decomposition.. The specimens were prepared by two stages: a) roas-tng
at 1,8000C of a WC and Ta205 mixture with carbon black; b) repeated pres5ing
and sintering of the carbide powders obtained at temperatures required to attain
complete solubility, and above. it Is shown that an increase of the preheating
temperature prior, to annealing extends considerably the incubation period, For
instance, a specimen roasted at i,850 0C (1.5 hours) decomposed after I hour
0 11-ed at 2,3500
annealing at 1,400 '3' but a specimen roas4 C did not decompose after
48 hour ann6aling at 1,6000C, The dispersity of carbide phases Is the higher

the incubation period. This is confirmed by the absence of partially deeomposed
crystals. In individual cases some crystals were observed, where the decompTsi-
tion had not as yet started, together with cases of complete decomposition.

ABSTRACT: The magnetic anisotropy of Un5G03 (hexagonal typo D88 structure) was mea-
sured. A 5 mm diameter spherical "pseudo-single crystal" was employed, i.e., a poly-
crystalline material consisting of large crystals with nearly parallel hexagonal
axes. Magnetization curves were obtained in the directions of greatest and least
susceptibility by a ballistic method at temperatures from 90 to 360,0K and magnatiz-~
ing fields up to 11 150 Oa. The curves of magnetization versus temperature at a
fixed nagnetizing field taken in the direction of minimum susceptibility for fields
less than 9000 Oe showed a slight rise of magnetization with temperature to a maxi-..
rum neaz the-Curio point;.,This rise is ascribed to the fact that m9gnetization in

thia direction is effoctod by rotation against-tho anisotropy forces, and the ani-
otropy decreases with increasing tomperaturo. The magnotocrystal anisotropy energy

was calculated from the area between the magnetization cu rves taken in the direc-
tions of maximum and minimum susceptibility.-This decreased monotonically from a
value (extrapolated) of 3.74 x 106 org/cm3 at OOK to zero at 3130K. The Curie point
is 300ox;'the anisotropy thus persists into the paramagnetic togion. The saturation:
magnetization extrapolated to OOK was 140 emu/g. Fr'om this a value*o:E 2.47 Bohr ma-
gneton, was calculated for the mean magnetic moment of Un. This is in agreement with~i
measurements of X.lCanematsu (J.Phys.Soo.Japan 17,35,1962). "The author expresses
his gratitude to S.S.Szezeniowski for his valuable discussions and for reading the

ABSTRACT: The effect of adding up to 25% Cr 3C2 on the properties of (Ti, W)C carbid
with a constant TiC;WC ratio of 35:65, was investigated. The initial (Ti, W, COC
carbides were synthesized from T102 + WC +,Cr203 + C powders in hydrogen at tempera-
tures from 2573 K for pure TiO + WC to 1923 K for carbide with 25% Cr C2. The car-
bide powders were compacted ani sintered in vacuum at 2073-2123 K. e porosity of
sintered compacts did not exceed 0.22. An x-ray diffraction analysis~revealed that
all the alloys have a solid-solution structure with an fee lattice. With increasing
Cr3C content oxidation resistance sharply increased.: The respective weight loss of
(TiW~C carbide and carbide containing 20% Cr3C2 was 72 and 3.62 of the original
weight in 10 hr at 1270 K. At 20% Cr C the resistivity increased by 60%, Young's
modulus dropped from 37 to 33 n/m2 .160. With increasing temperature from

composition. The coefficient of thermal expansion, bend strength, and contact angle
in wetting with Co in vacuum showed little or no change. Orig. art. has: 7 figures
