A FeCoNiCuAl high-entropy alloy was prepared by a novel method of microwave-assisted combustion synthesis,taking the oxides as raw materials and composition design of high entropy alloy and aluminum thermal reaction mechanism.The microstructure and room-temperature mechanical properties were investigated.The results show that the alloy forms dendritic structures and has simple FCC+BCC solid solution structure.Fe,Co,Ni,Al are evenly distributed in the alloy while Cu tends to segregate in the interdendritic s...
