中文摘要：通过Deform软件对SiCP/AZ61复合材料半固态触变成形过程进行数值模拟，研究了成形过程中的应力、应变分布和工作载荷规律，并且与常规态材料成形进行了比较。结果表明，SiCP/AZ61复合材料半固态触变成形具有变形抗力小，应力、应变分布均匀的特点，且材料流动性、充填性能都优于常规态材料，能够一次成形复杂形状零件。
英文摘要：Deform software was performed to simulate semi-solid thixotropic forming SiCP/AZ61 composite. The stress distribution, strain distribution and working load during the forming were analyzed by comparing with normal forming SiCP/AZ61 composite. The results show that SiCP/AZ61 composite has some advantages of small forming resistance, well-distributed stress and strain, the flow of materials, and the performance of forming are better than normal forming SiCP/AZ61, the complicated shape parts can be formed in one time deforming.
