Abstract Scope |
High entropy alloys (HEAs), a new class of metallic materials with more than one principal element, are being investigated for a broad range of potential applications. In this study, the microstructure and mechanical properties were examined of a transformation-induced plasticity dual-phase HEA Fe50Mn30Co10Cr10 (at.%) using microstructural and mechanical properties characterization tools including digital image correlation (DIC) and in-situ SEM tensile tester. The elastic behavior, strength, and ductility were determined from tensile test results. The Young’s modulus, strain distribution, and localized strain values in the gage length were evaluated from the DIC data. The gage section of the tensile specimens was analyzed to understand deformation mechanism(s). The localized strains in the gage section were found to be inhomogeneous. An in-depth discussion of deformation mechanism(s) will be presented based on the analysis of DIC and in-situ tensile test data. |
