摘　　要：在211Z.1铝合金拉伸试验的基础上,对筛选出来的缺陷试样进行了金相组织分析,重点探讨了针孔、缩孔、脆性相粗大、过烧等缺陷对铝合金性能的影响。发现缩孔组织对材料的力学性能影响最大,必须严格控制,同时优化热处理工艺参数,避免其他缺陷的产生。Based on the tensile test of 211Z. 1 aluminum alloy, the samples with defect were screened out by metallographic microstructure analysis, the influence of the defects, such as pinholes, shrinkage cavity, brittle phase coarsening and burning, on the properties of aluminum alloy was discussed. The results show that the shrinkage cavity organization has the maximum effect on mechanical performance, must be strictly controlled, additionally, the optimum parameters of heat treatment process to avoid other casting defects.
