Mechanical properties and deformation mechanisms of precipitation-strengthened heterogeneously structured FeNi-based medium-entropy alloy
Conventional high-performance superalloys typically rely on substantial amounts of costly Ni and Co, raising material costs and restricting widespread industrial use. We adopt a Fe-rich FeNi-based multi-principal element alloy with the nominal composition Fe40Ni30Co10Cr10Al5Ti5 (at.%) as a model system. Via heavy cold...
