Effects of rheocasting and heat treatment on microstructure and mechanical properties of A356 alloy

▶ The temperature range for solid-liquid region in A356 alloy is between 560 °C and 630 °C. ▶ The solid fraction increases from 0% to 100% with decreasing temperature. ▶ Pressures can break down the secondary dendrite arms result in grain refinement. ▶ Mechanical properties of rheocasting specimens have been improved.
