For most of Mg alloy, heat treatment could be utilized to raise the working performance and mechanical properties.
While the temperature and treated time in annealing homogenization are the most important factors to affect the grain structure and appearance.
However, it did not mean that the mechanical properties will always be improved with the temperature enhancement.
Nevertheless, the slight over-burned could not obviously affect the mechanical properties, as shown in Fig1(b).
Hence, the best mechanical properties could be obtained, when the optimum treated conditions could lead to both improvement of strength and plasticity which are affected by second phase contribution and grain size, respectively.
