摘要

以ZL102、纯铝、铜板、镁块为原材料熔配成ZL105合金。采用正交试验方法研究ZL105合金挤压铸造工艺参数对成型件力学性能和显微组织的影响。结果表明

挤压铸造工艺参数对合金强度影响的程度大小依次为:合金浇注温度、保压时间、比压;对塑性影响最大的是合金浇注温度。合金浇注温度是对铸件的性能和显微组织影响最为显著的因素。金属型铸件热处理后的抗拉强度为225.0MPa

挤压铸件热处理后的抗拉强度平均达到249.8MPa

抗拉强度较金属型增加了11.0%。

Abstract

ZL105 alloy was prepared with ZL102 alloy

pure aluminum

copper plate and Mg ingot.Effects of processing parameters on the mechanical properties and microstructure of squeezing castings were investigated by orthogonal testing.The results show that the influencing factors on strength of the squeezing castings are as follows:pouring temperature

holding time

pressure

and dominant factors on plasticity is pouring temperature.The dominant factor influencing mechanical properties and microstructure of the squeezing castings is pouring temperature.Tensile strength of the permanent mold castings after heat treatment reaches 225.0 MPa

while tensile strength of squeezing casting after heat treatment reaches 249.8 MPa

improved by 11.0%.
