Mechanism of Combustion Synthesis of TiC-Ti Cermet

摘要

In order to investigate the mechanism of combustion synthesis of TiC-Ti cermet,a mixture of Ti and C was used for a combustion front quenching test,and the microstructural evolution in the quenched sample was analyzed by scanning electron microscopy (SEM) and energy dispersive X-ray (EDX). Also,a temperature-time profile of the combustion reaction was measured. Based on the experimental results,a reaction-dissolution-precipitation mechanism of the combustion synthesis of TiC-Ti was proposed.
