Abstract Scope |
The FeCrNi equiatomic medium entropy alloy has received attention as a cost-effective class of high/medium entropy alloys. The material shows the single FCC for the annealing temperatures higher than 900 ℃ while the Cr-rich BCC phase is formed in the FCC matrix for the annealing temperatures lower than 900 ℃. The BCC phase shows characteristic equiaxed and rod morphology depending upon annealing temperatures. For the annealing temperatures ranging from 700-900 ℃, a mixed equiaxed and rod-shaped BCC phase is present. Thus, we focus on microstructure evolution and mechanical properties of the materials with increasing annealing time at 800 ℃. The BCC phase fraction saturates in the annealing condition of 5 h at 800 ℃. Further, recrystallization is sluggish due to the presence of the BCC phase in the FCC matrix. We discuss the detailed microstructure-mechanical properties relationship of the investigated materials. |
