Abstract Scope |
The multicomponent alloys, also known as High Entropy Alloys (HEAs), have been the subject of intense exploration for over a decade now for a wide range of potential applications. To investigate microstructure – mechanical property correlation in a newly developed transformation-induced plasticity (TRIP) dual-phase high-entropy alloy (DP-HEA), Fe50Mn30Co10Cr10, microstructural analysis, mechanical testing, and fractography were performed on the DP-HEA using advanced microstructural and mechanical properties characterization tools including digital image correlation. A variation in the hardness values was observed possibly due to the presence of two different phases in the microstructure. The yield strength, ultimate tensile strength, and % elongation were estimated from tensile test results. The fractography of the fractured tensile specimens revealed ductile fracture of the alloy. The strain distribution, in the gage section, was found to be inhomogeneous probably due to differences in the deformation of crystals with different crystallographic orientations, phases, or both. |
