Abstract
Mixtures of titanium powder and alumina or carbide (SiC, TiC or WC) powder were resistance-sintered. Up to 2vol% alumina, 10vol% SiC, 20vol% TiC and 20vol% WC, sound compacts were obtained, and with increase of volume fraction of alumina or carbide, the elongation decreased and the hardness and the electrical resistance of specimens increased. When the volume fraction was 1 vol% alumina or 2 vol% carbides, the maximum tensile strength (alumina 102 kg/mm2, carbides 83-86 kg/mm2) was obtained. Influence of volume fraction of added particles on the various properties was discussed in relation to dispersion behavior of added particles and a reaction between titanium and alumina or carbide.
