✦ Synopsis

A high entropy alloy of Ti0.5CrFeNiAlCo can form two BCC crystal structures, one is with larger lattice parameter, and another with smaller one. In this paper, more Co was added in the Ti0.5CrFeNiAlCo alloy to detect the crystal structure and the properties changes. It is found that, with the increase of Co addition, the smaller BCC prefers to transit to FCC firstly, and the compressive strength deceased slightly.

The microstructures of the prepared Ti(C, N)-based cermets with various TaC additions were studied using X-ray diffractometry (XRD) and scanning electron microscopy (SEM). Mechanical properties such as transverse rupture strength (TRS), fracture toughness (K 1C ) and hardness (HRA) were also measure
