M23C6 precipitation strengthened Fe0.6MnNi1.4 medium entropy alloy matrix composites

Here, judicious heat treatment is used to enhance the mechanical properties of 5 vol%TiC/Fe0.6MnNi1.4 composites. After annealing at 1100 °C, M23C6 (M = Fe, Mn, Ni) precipitates formed, imparting the composites remarkable mechanical properties, with the ultimate tensile strength and ductility determined to be 805.5 MPa and 51.1%, respectively.
