Abstract
A process of heat treating an Al—Si—Cu—Mg—Fe—Zn—Mn—Sr-TMs alloy, where the TMs include Zr and V, includes heat treating the alloy to produce a microstructure having a matrix with Zr and V in solid solution after solidification. The solid solution Zr, in wt. %, is at least 0.16%, the solid solution V, in wt. %, is at least 0.20% after heat treatment, and Cu and Mg are dissolved into the matrix during the heat treatment and subsequently precipitated during the heat treatment. The composition of the alloy, in wt. %, includes Cu between 3.0-3.5%, Fe between 0-0.2%, Mg between 0.24-0.35%, Mn between 0-0.40%, Si between 6.5-8.0%, Sr between 0-0.025%, Ti between 0.05-0.2%, V between 0.20-0.35%, Zr between 0.2-0.4%, maximum 0.5% total of other alloying elements, and balance Al.
