摘要
Abstract
A FeCoNiCuAI 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 structure. The yield stress, compressive strength and plastic strain of the alloy reach 1 116MPa, 1 312MPa, and 11.4% , respectively. Besides, the microhardness value is 517HV.关键词
