Microstructural evolution and strengthening mechanisms of a novel Al–11Si–3Cu alloy microalloyed with minor contents of Sr and Sc

Alloying technology usually improves the mechanical properties of alloys; however, the high cost of alloying elements limits their wider applicability to conventional cast aluminium alloys. In this work, a novel high-strength, ductile, and low-cost Al–11Si–3Cu alloy microalloyed with minor Sr + Sc w...
