Mechanical propertiesProduction failuresAn aluminum foundry experienced frequent failures of A357-T6 aluminum castings. These failures are manifested in attaining tensile stresses and total percentage elongation below the minimum requirements of MIL-A-22180D. Sixteen heat treatments were designed to study ...
This leads to high performance material properties with an improved strength and ductility compared to conventional production routes of the same alloys. In this study, the mechanical behavior of an RHS-sintered age-hardenable A357 (AlSi7Mg0.6) cast alloy and a SiCp/A357 alumi...
Si particlesWeibull analysisQuality IndexThe effect of 1wt% Cu additions as well as minor alloying additions of Sm, Ag and Sr on the Si particle size and aspect ratio as well as tensile properties was investigated in this study. Results showed that all alloying additions decreased elongation ...
