Abstract
The properties, performance, and reliability of a cermet material depend mostly on the
intrinsic properties influenced by microstructure that evolves during processing and use. In this
study, the effect of microstructure on reliability of multiphase materials in erosive media is
analyzed with reference to WC-, TiC-, and Cr3C2 - based ceramic-metal composites. Microstructure
of multiphase materials, fracture mechanisms, ability of energy dissipation, thermo-mechanical
parameters and erosion resistance are examined. It has been shown that microstructural variables
play a very important role in cermets performance. The energetic criterion of non-homogeneous
materials selection has been presented.
