Microstructure evolution and mechanical properties of (CoCrNi)90(AlTiZr)5(CuFeMo)5 multicomponent alloy: A pathway through multicomponent alloys toward new superalloys

Thermodynamic criteria of lattice distortion energy (ΔHel) and enthalpy of mixing (ΔHmix) were considered to design and estimate the initial phase formation and stability in (CoCrNi)100−x−y(AlTiZr)x(CuFeMo)y multicomponent alloy (MCA) system. This study aimed to chase a new alloy design pathway to develop superalloys by benefitting from the concept of multiphase MCAs. The non-equilibrium cast microstructure (CoCrNi)100−x−y(AlTiZr)x(CuFeMo)y...
