HIGH TEMPERATURE DUCTILITY OF TiC AND THE EFFECT ON CYCLIC THERMAL SHOCK DAMAGE OF TiC/Ni3Al FGM
-
Abstract
The high temperature ductile deformation behavior of TiC sintered body with various content of Cr3C2 addition was investigated. The results show that the descending trend of the effective conductivity of TiC/Ni3Al FGMs with the numbers of shock cycles relates closely to the ductile deformation behavior of TiC, and the vertical cracks appearing on the TiC surface is caused by large radial compressive stresses.
