摘要

The microstructure and compressive properties of AlCoCrCuFeNi high-entropy alloy aged at temperatures ranging from 500 to 1000 °C were investigated. The BCC and FCC phase structures remain unchanged after aging the AlCoCrCuFeNi alloy at temperatures below 645 °C. Aging the alloy at elevated temperature causes the structure gradually to transform from stabilized BCC to FCC. Also, as the aging temperature increases, the yield strength of the material decreases but plastic strain increases. When the alloy was aged at 1000 °C, the plastic strain even reaches 27%.
