摘　　要：采用ZL116合金进行了半固态触变成形试验,结果表明,应用半固态触变成形工艺可以获得组织致密、轮廓清晰、充型完整的成形件;成形件的微观组织主要为细小、分布均匀的近球状和蔷薇状非枝晶组织;成形静压力作用所引起的局部组织塑性变形,使成形件的组织与性能得到改善,与液态触变工艺相比,硬度提高20%。The semisolid thixoforming tests on ZL116 alloys were carried out, The results showed that the parts of ZL116 alloy prepared by semisolid thixoforming are more compact, clean-cut and full-filled, Its microstructure is mainly composed of the fine near-spherical and rosette non-dentritic grains homogeneously distributed, And the properties of parts are increased obviously because of the partial plastic deformation caused by the steady deformation force.
