Properties of AlFeNiCrCoTi0.5 High-Entropy Alloy Particle-Reinforced 6061Al Composites Prepared by Extrusion

(AlFeNiCrCoTi0.5)p/6061Al matrix composites were prepared by cold isostatic pressing combined with equal-diameter angular extrusion. The microstructure and properties of the extruded materials after adding high-entropy alloys studied. FCC + BCC dual-phase alloy particles mechanically alloyed for 90 h added to aluminum matrix, while composite material formed a diffusion interface Compared 6061Al when content AlFeNiCrCoTi0.5 was 10%, two passes, hardness increased from 52.5 HV 70.3 HV, tensile strength 158 MPa 188 MPa, elongation changed 14.9% 14.1%. had good comprehensive mechanical properties.
