Abstract

The peculiarities of structure and phase composition of the briquettes material obtained by thermal fusion of the mixture consisting of a powder slurry obtained by grinding rollers and cone bearings, titanium hydride and graphite. It was shown that after synthesis at temperatures of 1150÷1200 ⁰С phase composition of the obtained alloy includes mainly phases of titanium carbide, cementite and α-Fe. When boron carbide introduced into the mixture too, the last dissociates during thermal synthesis, resulting along with titanium carbide in the alloy significant content boride phases - TiB, TiB₂, Ti₂B₅ and FeB was identified.
