Abstract

Cermets were produced by a technology including pressing and sintering of titanium carbide T_iC_x (0.7 < x < 0.98) preforms and molten tool steel infiltration. So-called "graded" cermets were produced using a controlled distribution of TiC_x with different x. The resultant redistribution of alloying elements between the steel and TiC _x during both the infiltration and following heat treatment was very essential. The changes of both steel and TiC_x compositions produce changes in the process of austenitization, carbide dissolution and precipitation, and martensitic transformation. Both the strength of the material and the gradient of properties in graded cermets can be controlled using both kinetic factors of element redistribution and structure changes caused by the heat treatment.
