Abstract

Fully densified in-situ reinforced (TiB + TiC)-Ti matrix composites have been produced from TiH₂-B₄C mixtures using pressure less sintering or hot pressing technique. With increasing content of reinforcing components the sintering is retarded. The materials with more than 20 - 30 vol. % were only completely densified by hot pressing technique. Hardness values of the Ti matrix composites produced are up to 5 times higher than that of the sintered pure Ti produced from TiH₂. This is caused beside the higher hardness of the inclusions also by hardening the matrix due to solubility of B and C in the titanium.
