Abstract Scope |
FeMnCoCr based high entropy alloys (HEA) are one of the prominent, metastable, multi-component systems that exhibit the unique behavior of transformation induced plasticity (TRIP). The emergence of HCP phase leading to martensitic microstructure during deformation from the metastable parent FCC solid solution phase provides the much-required phase-interface strengthening without compromising the ductility. However, to further improve the mechanical properties of these metastable alloys especially the yield strength, the TRIP effect alone appears to be not sufficient. Hence, this presentation will focus on the experimental design aspects including combinatorial synthesis of compositionally tailored alloys that can exhibit unique microstructures with concomitant precipitation strengthening in FeMnCoCr based HEA system. The crucial challenge of inducing nanoscale precipitate phases that are chemically homogenous in the metastable, FCC structured, low-stacking fault energy solid solution matrix without disturbing its unique behavior of TRIP will be discussed. |
