Optimization of mechanical and tribological properties of FCC CrCoNi multi-principal element alloy with Mo addition

A new multi-principal element alloy system, CrCoNiMox, is designed by adding Mo in FCC CrCoNi alloy to improve the strength and wear resistance. The addition of Mo causes severe lattice distortion of the alloys and promotes the formation of intermetallic phases. With the increase of Mo content, the hardness and compressive yield strength of the CrCoNiMox alloys increase obviously from 244 HV and 518 MPa to 656 HV and 1973 MPa, respectively,...
