【Abstract】 The influence of alloy composition on the effect of ZAlSi7MgA alloy has been analyzed and optimal composition design been proposed. By adopting Sb Te compound metamorphism treatment, the alloy property has been improved. The comparative experiment and the orthogonal analysis method have been done on the thermal treatment of the alloy; the best thermal treatment plan has been obtained. Through the metamorphism treatment of ZAlSi7MgA alloy and the optimization of thermal treatment technology, the composite mechanical property of the alloy has been improved and a fine enduring metamorphism property been achieved.更多还原
