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).
