Abstract: Effects of hot rolling on microstructure and mechanical properties of a cast Al–Si alloy have been investigated. The hot rolling was carried out at 330°C with rolling reductions ranging from 0 to 80%. With increase in the rolling reduction, the shrinkage cavity decreases in size and volume fraction, and also the eutectic Si particles decreased in size and distance between the particles. In the hot rolled samples, the Al matrix phase consisted of recrystallized grains of which size is comparable to the distance between the eutectic Si particles. Ultimate tensile strength of hot rolled sample increased nearly 33% compared to the one without hot rolling. Elongation of hot rolled sample was about 4.5 times higher than the one without hot rolling.
