HEAs were prepared by gas atomization with the following steps. Firstly, the pure metals (Fe, Mn, Co, Cr and Ni) with high purity (≥99.9%) were melted at 1500 °C in an induction heated vacuum furnace. Then, the molten liquid metal was sprayed through Al2O3 ceramic tube with the nozzle hole diameter of 3.5 mm under high-purity (≥99.9%) Ar atmosphere at 4 MPa. Finally, the obtained powders were......
