聚焦于高真空压铸结构件性能测试过程中伸长率的影响,通过深入分析平板模、试棒模以及实际结构件的力学性能,探讨了材料成分对免热处理合金的强韧作用,重点研究了取样方式和铸件结构设计对铸件力学性能的影响。对高强韧铝合金在测试过程中的试片类型、标距大小等关键因素进行分析,提供了获取材料理想性能的测试方法与建议。此外,系统比较了传统AlSi10MnMg热处理材料、高强韧免热处理材料在铸件本体取样与材料理想性能之间的波动偏差。

Centered on influencing of elongation on high vacuum die-casting structural components during the perfor⁃mance testing process,mechanical properties of flat plate molds,test bar molds,and structural components were inves⁃tigated in depth.Toughening effects of composition on heat-free alloys were explored,and the significant effects of sampling methods and structural design on mechanical properties of the alloy were emphasized.Key factors such as specimen type and gauge size of aluminum alloys with high strength and toughness during testing process were ana⁃lyzed,providing testing methods and suggestions for obtaining ideal properties.In addition,the fluctuation deviation between body sampling and ideal properties of traditional AlSi10MnMg heat treated materials and heat-free materials with high strength and toughness were analyzed comparatively.
