On influence of Ti and Sr on microstructure, mechanical properties and quality index of cast eutectic Al–Si–Mg alloy

Effects of Sr content on the microstructure and mechanical properties of cast Al–12Si–4Cu–2Ni–0.8Mg alloys

“…[33]. Q is defined as a semi-logarithmic plot of ultimate tensile strength versus the elongation to fracture and it is expressed as follows [34]:…”

Effect of Cr content and heat-treatment on the high temperature strength of eutectic Al–Si alloys

“…The eutectic Al-Si based casting alloys are widely used in automotive applications (E.g., piston production) due to their good castability, high strength, light weight, good wear resistance and low thermal expansion [1][2][3][4] . However, it is well-known that the pistons are working under very extreme and complicated environment, and the materials used for pistons should be able to withstand the temperatures from 350 to 400 o C, Therefore, the superb high temperature (HT) strength of such alloys is the important design criteria [5,6] .…”
