A study of the mechanical properties of an Al-Si-Cu alloy (ADC12) produced by various casting processes

► We examine mechanical properties of Al alloys produced by several casting processes. ► The mechanical properties obtained are different depending on the casting process. ► The mechanical properties are related to the lattice mis-orientation angle. ► The tensile strengths are evaluated by Hall-Petch relations. ► The fatigue properties are explained by power law dependence.
