investigated. According to A.D. Kramarov fRef 1
_
librium temperature for the reduction of chromium oxide by
carbon under atmospheric pressure occurs at about 1,4000C-
Experiments of the author have also shown that the full re-
duction of chromium oxide is obtained atl,350 to 1,400OC-
The temperature of reduction is lowered to 1,150,to 1,2500C
when the mixture Fe20
is reduced by carbon. It is

ABSTRACT: From a survey of investigations on -the production of
heat-resisting and non-scaling alloys based on
refractory-metal borides the authors formulate five
principles for such work. The main items in these are
as follows. 1): The strength and plasticity of these
alloys depend on,the nature of the reaction of the borides:
with the alloying elements; if the reaction products
are eiitectics low:melting compared with the"Doride base
the strength and plas-ticity rise. 2) The heat-
resisting properties of borides remain high if they are---,
alloyed with dher high-melting borides or silicides, ', or
with refract-ory metals forming with borides high-
,.emperature eutectics (ZrB
2 +` MO), ~(Ti. Cr)B;2 +- ZrB2.
3) Res1stance to oxidation of beride alloys is increased-

4) Brittleness can be reduced by reducing bonding forces,,
in the boride base crystal lattice by dissolvine; less

ABSTRACT: The properties of ZrB 2- Mo alloys obtained by sinter-
ing were investigated. On the basis ofthe results of vi-
sual thermal analysis, metallographic and roentgenographic
studies. shr inkage curves, and measuring the macro- and
microhardness, a hypothetical diagram of the ZrB2-Mo sys-
tem state was composed. The existence of.the triple bor-
ide Mo ZrB was discovered in the system. Conditions for

the hot pressing of zirconium boride alloys with molybden-
um were studied at molybdenum contents of 5; 40 and-60 mol-

ABSTRACT: Investigations of magnetic susceptibility of metal-like com-
pounds can contribute to an explanation of the nature of
chemical bounds in these phases. The authors investigated
the magnetic susceptibility of the single-phase solid solutions
of the following metal-like compounds: ZrC-NbC,- TaC-NbC;
TaB2-ZrB2 and TiC-TiN. Since the measurements of absolute
susceptibility were difficult due to experimental conditions,
the values of relative susceptibility were determined by
taking that of one of the components for unity. The results
of experiments are presented in graphical form showing the
dependence of magnetic susceptibility on the.concentration.
The two curves for the alloys NbC-ZrC and TaB2-ZrB2 have peaks,
Card 1/2 whereas the curve for NbC-TaC does not possess a peak. In

the alloy TiC-TiN, a sharp fall of the magnetic susceptibility
is observed with increasing TiC concentration. The authors
attempt to interpret theoretically these experimental data.
There are 2 graphs and 5 references, 3 of which are Soviet,

Carbides, borides, nitrides and silicides of.high-melting metals
and some non-metals are very resistant to wear, corrosion, and
heat. Tile principal physical properties of these compounds are
Uiven in Table 1. Titanium carbide is not affected by con-
centrated hydrochloric and sulfuric acid. The-carbides of
boron and silicon are even resistant to boiling acids. Boron
nitridc 'is resistant to chlorineat'7000C for 40 hours, to
oxidation at the same temperature for 60 hours. Silicon
nitride shows no changes after 500 hours in hydrochloric,
nitric, sulfuric acid, etc. The highest resistance to.acids.
have silicides, among them molybdenum disilicide, NoSi2. It
is resistant to melted sodium, lead, bismuth, etc. Porider
