Abstract

In this study, it was investigated fabrication of high entropy alloy containing 25 wt.% Fe, 25 wt.% Co, 25 wt.% Cr, 15 wt.% Ni, 10 wt.% Al via Electric Current Activated (Assisted) Sintering (ECAS) process and effect of heat treatment (annealing) on sintering samples. Heat treatments were performed in open atmospheric furnace at 900, 1000 °C for 10 hours. Microstructures of sintered and heat treated samples were investigated by optic and scanning electron microscopes, phases in samples were analyzed by XRD and their hardness was measured by Vickers hardness tester ranged from 291 to 977 HV.

Keywords: High entropy alloys, FeCoCrNiAl alloy, ECAS, heat treatment, hardness
