I observed a 39 degree two theeta peak in my XRD pattern for my equiatomic FeCoNiAlMn high entropy alloy powder after 45hrs mechanical alloying and same after 50 degree two theeta also but not getting which phase is it either BCC or FCC solid solution phase? I have attached jpeg of my FeCoNiAlMn high entropy alloy powder system. It's XRD pattern is represented in red color.
