Abstract
Dissolution of Mg2Si particles and homogenisation in aluminium foundry allo ys A356 and A357 have been simulated by a simple numerical diffusion model. The model predicts that dissolution and homogenisation are complete after solution treatment times of less than one hour at 540 degrees C for both al loys. Model predictions have been verified by metallography.
