摘要

对铝合金铸件与海绵状疏松、分散疏松的疏松等级与力学性能的关系进行了系统研究。试验表明，疏松等级与力学性能之间呈线性相关关系

Abstract

The effects of sponge porosity and scattered porosity grades on mechanical properties in aluminum alloy castings have been studied in this paper. Result shows that the ultimate tensile strength decreases and the elongation decreases greatly with increasing the grade of porosity.
