铸件表面及内部无铸造缺陷

微观组织致密

综合力学性能较好。铸件的抗拉强度可以达到370 MPa

伸长率为2.5%

硬度（HB）为128。

Abstract

ZL111aluminum alloy scroll plate of the automotive refrigeration compressor was produced by squeezing casting.The effects of process parameters on mechanical properties and microstructure of the scroll plate were investigated by the single variable method.The results reveal that the castings have absence of casting defects with dense microstructure and satisfied comprehensive mechanical properties in the optimum process parameters（casting pressure of 100 MPa

holding time of 16 s

pouring temperature of 740 ℃）.The tensile strength

elongation and hardness of aluminum alloy scroll plate specimen can reach 370 MPa

2.5% and 128 HB

respectively.
