摘要：
AlxCrFeNi2.5Mo high entropy alloys (HEAs) were fabricated. Investigations were done into how Al content affected phase development, microstructure and mechanical characteristics. As the amount of Al growing, the phases constitution of AlxCrFeNi2.5Mo HEAs altered from face-centered cubic (FCC) + s phase to FCC + body-centered cubic (BCC) + s phase, and the microstructure varied from hypoeutectic to dendrite + interdendritic + eutectic structure. The Al0.2CrFeNi2.5Mo HEA had an exceptional overall performance with high tensile strength and compression strength of 1160 MPa and 1728 MPa, and good fracture strain and plastic strain of 8.0% and 22.3%, respectively.
