Abstract
Yield strength of titanium carbide particle dispersion strengthened nickel alloys were measured in the temperature range of 800°to 1100°C by use of compression tests. Samples were prepared through the melting-pressing and HIP treatments from the hot pressed materials.
The yield strength of HIP samples lineally increased with increase of titanium carbide content from 10 to 40%, but that of melting-pressing sample showed maximum near 30% of titanium carbide.
It was found from SEM observations that titanium carbide particles grew and turned into spherical shapes due to melting treatment.
