In al and si if temperature is changed
WebThe aluminum alloy tested in this study is the casting alloy (Al-Mg-Si-Cu). Generally, this alloy is thermally aged when exposed to high-temperature environment, and the precipitations (such as Al 2 Cu, Mg 2 Si) are created and transformed, which is reduced to the change of elastic property. Resultantly, the curvature in the stress-strain curve ...
