Influence of the chemical composition of titanium carbide on the high-temperature properties of cemented carbides produced by impregnation [[Previously Titled: The effect of chemical composition of titanium carbide on high-temperature properties of hard alloys obtained by impregnation.]]

Previously abstracted from original as item 199503-54-0281. The problems on creation of new high-temperature hard alloys by impregnation of porous frames are considered. It is shown that high density in hard alloys with the frame structure may be attained by means of control of the ductile-brittle transition temperature of a refractory phase. Varying microstructure and chemical composition of the frame, as well as porosity and impregnating material, it is possible to synthesize new hard alloys for particular ranges of working temperatures.
