Study of the stabilization process of gas atomized Al0.5CoCrFeNi2Ti0.5 high-entropy alloy in phase transformation

•Characterization of Al0.5CoCrFeNi2Ti0.5 powders produced by the gas atomization method.•Phase constitution of Al0.5CoCrFeNi2Ti0.5 powders transferred from BCC to FCC-dominated structure on annealing treatment.•EBSD and EDS results indicate that precipitates were of (Al, Ti)-rich whereas the matrix...
