Abstract

The Co55Cr40Ni5 multicomponent alloy was designed to be single-phase face centered cubic (FCC), display high strength, and have the ability to undergo transformation-induced plasticity (TRIP) during plastic deformation. The alloy was produced, and phase stability was monitored in-situ by synchrotron X-ray diffraction during thermomechanical deformation to observe the formation and evolution of the hexagonal close packed (HCP) martensite phase as a function of applied stress. The alloy displays a good combination of strength and ductility, owing largely to the TRIP effect, which increases the strain hardening rate during deformation. (C) 2019 Acta Materialia Inc.
