ZL201合金半固态触变压铸的组织与性能
Microstructure and Property of ZL201 Alloy by Semi-Solid Thixodie-Casting
摘要
Abstract
The microstructures and properties of semi-solid die-casting ZL201 alloy were investigated, including semi-solid ingot preparation, reheating, die-casting forming, solution and aging treatment, etc. The results show that the homogeneous, fine and non-dentritic microstructure can be successfully obtained by low frequency electromagnetic stirring semi-continuous casting. The microstructure is gradually turned into near-spherical grain, which is suitable for thixodie-casting by remelting at 630 ℃ for 20 min. The microstructure of the semi-solid thixodie-casting part consists of coarse rod or near-spherical primary solid phase and fine dentritic or equiaxed second solid phase, but more compact than that of the conventional die-casting part. After treatment, i.e. solution at 535 ℃ for 9 h and aging at 175 ℃ for 6 h, the hardness of the semi-solid thixodie-casting part is HV 116.6.关键词
