Description

When large TiC particles (30 microm in average) are embedded in Cr3C2 powders and heat-treated at 1,550 C, recrystallization occurs from the surface of the TiC particles, and they are finally replaced by an entirely new set of (Ti,Cr)C alloy grains. The observed recrystallization is greatly suppressed when ZrC is added in the Cr3C2 matrix. The results are in agreement with the prediction that a lattice mismatch due to the diffusion of Cr and resultant formation of misfit dislocations are the major cause of recrystallization. The diffusion induced recrystallization (DIR) process is observed in detail by using a transmission electron microscope
