| Abstract: | Low temperature aging for die casting Al alloy under appropriate technological condition can increase average strength and Brinell hardness more than 10% and 30% respectively. By means of this treatment it is possible to aviod deformation and bulge casting defects in solid solution treatment at high temperature as well as to increase mechanical properties for die casting. Microstructure observations during the period of aging treatment by SEM have been examined. |
