Abstract: The Mg-Al-Zn series AZ31 and AZ314+MM alloys are homogenized at 673, 723 and753K respectively. The hardness of alloy ingots at different heat-treated states ismeasured and the microstructures are observed. The optimum annealing temperatureis 723K and the time is 12h.

Key words: magnesium alloy, homogenization, diffusion
