Abstract:

The casting method was employed to produce high entropy alloy. In this regard, the fabrication and characterization of recently developed dual phase high entropy alloy has been documented in the present study. The initial ingot was cast in vacuum induction furnace to predetermined composition of 50Fe-30Mn-10Co-10Cr (at. %). The phase identification was done by XRD analysis which approves the formation of two phase microstructure. Dual phase microstructure including FCC and HCP phases were formed. This is in agreement with the phase formations rule of high entropy alloys. By altering the cooling rate the initial HCP phase changes significantly. In addition, the initial FCC grain size can affect the martensitic transformation during cooling effectively. The coarse grain microstructure leads to the formation of martensite in different morphologies.
