摘　　要：通过对AlSi5Cu3Mg合金半固态成形过程三个阶段的实验分析,初步探索了该合金适合半固态成形的工艺参数,并和A356合金做了半固态成形三个阶段的比较。结果表明,AlSi5Cu3Mg非树枝晶坯料和感应加热后的坯料均满足半固态成形的条件,且其压铸件具有较优异的力学性能。By analyzing three phases of semi-solid forming of A1Si5Cu3Mg alloy, the suitable process parameters of this alloy were researched, and three phases of semi-solid forming of A356 alloy and A1Si5Cu3Mg alloy were compared. The results show that the A1Si5Cu3Mg non-dendrite blank and the blank after induction heating meet the semi-solid forming conditions, and the die castings have excellent mechanical properties
