Abstract

This study investigated the tensile properties of spray-formed (SF) and ingot-cast (IC) high-Si aluminum alloys which suffered from cyclic heating/cooling. Due to the breakup of massive primary Si particles, the strength of the IC specimens descends gradually with an increasing number of thermal cycles. The uniform and refined structure of the SF specimens displays ductile fracture pattern and retains a similar tensile behavior even after a great number of heating and water quenching.
