Abstract
The application of dynamic pressure to the forming of titanium carbide cermet has been studied. The TiC-20wt%Ni and TiC-l5wtooNi-5wt% Mo cermets with high density were obtained by impact forming with high energy (142-200 kg-m/cc) and at high temperature (1100°C-1280°C), and by subsequent annealing at 1200°C for 90 minutes. Density and hardness of the obtained cermets are higher than those of normally sintered ones, with almost the same transverse strength. Excellent results were obtained at cutting performance test also. The microstructures were fine and dense, because the annealing temperature was lower than that in normal sintering so that grain growth was retarded.
