Microstructural Evolution During the Infiltration Treatment of Titanium Carbide‐Iron Composite

Abstract

The microstructural evolution of grain‐matrix interfaces in TiC‐Fe cermet has been observed and explained in terms of equilibration reaction and interfacial energy minimization. The coherency strain energy is assumed to be the driving force for enhanced dissolution of certain specific planes, which results in a very irregular grain shape. The equilibrium shape appears after heat treatment for a long period.
