## Abstract With dualβsized SiC particles, a 70 vol% SiCp/pure Al composite was fabricated by squeeze casting technology. The composite was subjected to a thermal cycling test between 20 and 150Β Β°C. A large residual tensile strain was observed at the end of the first cycling, but the residual lengt
The effects of systematic changes in reinforcement size and matrix microstructure on the crack initiation and growth toughness of a 7091 aluminum alloy reinforced with SiC particulates were studied. It is shown that changes in matrix microstructure have a significant effect on both initiation and gr
