Methods of optical metallography, X ray diffraction analysis, scanning electron and transmission diffraction microscopy were applied to study deformation and fracture mode in WC-110G13 steel cermet after various heat treatments resulted in stable or metastable states of austenitic constituent. Metastable austenite possesses higher deformability and can transmit external load to carbide constituent. The latter is deformed together with steel matrix. This makes it possible to obtain composite material that has simultaneously high values of hardness, strength and ductility.
