Part of the The Minerals, Metals & Materials Series book series (MMMS) Abstract In this work, a modified Al–Si–Mg (A356) alloy was prepared by vacuum-assisted high pressure die casting processes (V-HPDC). To release residual stresses, various thermal treatment schemes over a wide range of temperatures between 120 and 350 °C were experimented to the as-cast V-HPDC alloy, in

Processing conditions such as cooling rate and pressure level greatly influence the
International Journal of Metalcasting (2023)Cite this article Abstract Non-heat-treated Al–Mg-based die casting alloys have been developed for the structural parts of automobiles. In previous studies, alloy compositions with at least 1.0%Si have been proposed to reduce the hot tearing susceptibility (HTS). On the other hand, the increase in the Si content reduces the ductility. For some
