| 英文摘要 | Dual or multi-phase high-entropy alloys (HEAs) with nano-precipitates are of great importance to overcome the strength-ductility tradeoff of structural materials. In this work, Al0.5CrFeNi2.5Si0.25 HEAs were designed and fabricated using vacuum induction melting. The microstructure, phase evolution and compressive behavior of Al0.5CrFeNi2.5Si0.25 HEAs before and after annealing at various temperatures (750 degrees C, 850 degrees C, 1050 degrees C, and 1200 degrees C) were investigated. The as-casted and annealed Al0.5CrFeNi2.5Si0.25 HEAs constitute a dual-phase (FCC and BCC) composition with L12 and sigma phases. With increasing annealing temperature (750 degrees C-1200 degrees C), the proportion of the BCC matrix containing Cr-rich nanoparticles and strip-shaped sigma phases gradually increased. The Cr-rich nanoparticles were gradually refined. Partial sigma phase dissolved after heat treatment at 1050 degrees C and 1200 degrees C. The variation of the precipitated phases at different temperatures led to the occurrence of strengthening, which makes the alloys overcome the tradeoff between compressive strength and ductility. Under the 750 degrees C-1200 degrees C annealing, the compressive strength increased from 2288 MPa to 2584 MPa, accompanied by an increase in fracture strain from 14.9% to 23.4%. |
