Abstract

TiC and TiC-Ni3Al composites were prepared by hot-pressing at 1573K. Cr3C2 was added as a sintering aid. Fully dense (more than 97% theoretical density) bodies were obtained by 3 vol% Cr3C2 addition. The thermal conductivity( κ) of TiC-Ni3Al composites decreased with increasing Ni3Al content in general, however, the maximum of κ values was observed at 40 vol% Ni3Al. The microstructure of 40vol% Ni3Al composite (i. e., network structure) was different from that of other compositions (i. e., Ni3Al or TiC particles dispersed).
