摘要 | In this paper, high-Si reinforced Al matrix composites (H-Si/Al) with Si mass ratio 50-70% were successfully fabricated from the powder mixture of Si and Al by a novel route called as powder semi-solid squeeze. It is found that no Al-Si lamellar eutectic in the composites. As the Si content increases, fine Si particles in the H-Si/Al are reduced and the coarse Si particles may increase in size, or gather together to form twisted large particles and even form a space network structure. With the Si content ranging from 50% to 70%, The flexural strength varies between 248 and 179 MPa, the mean coefficient of thermal expansion from ambient temperature to 100 degrees C can be regulated between 11.32 and 7.55 x 10(-6) degrees C-1, and the thermal conductivity varies between 140 and 120 W m(-1) degrees C-1, showing that H-Si/Al prepared by powder semi-solid squeeze have excellent mechanical and thermal properties.
