Abstract

Thermal explosion method was employed to create TiC-based cermet with medium-entropy NiCoCr binder. The process involved heating a mixture of mechanically alloyed NiCoCr powder, Ti, and C in argon. Pre-explosion analysis revealed solid-phase diffusion of Ti and C into NiCoCr lattice, leading to subsequent reaction. Microstructural comparisons were conducted between cermets derived from mixtures utilizing NiCoCr alloy binder and those employing starting metal mixture (Ni + Co + Cr).
