摘要
采用扫描电子显微镜、能谱分析仪以及万能电子拉伸试验机等观察并研究T6热处理对17vol%SiCp/2009Al复合材料微观组织结构及静力学性能的影响。结果表明:T6热处理工艺会使Cu元素等在铝合金基体中分布更加均匀。T6热处理之后复合材料的弹性模量基本不变,屈服强度提高了51.67%,抗拉强度提高了75.93%,延伸率下降了54.19%。
The effect of T6 heat treatment on the microstructure and mechanical properties of 17vol%SiCp/2009Al composites was observed and studied by means of scanning electron microscopy,energy spectrum analyzer and universal electronic tensile tester.The results show that the T6 heat treatment process enables the elements like Cu to become more uniformly distributed in the aluminum alloy matrix.After T6 heat treatment,the elastic modulus of the composite material remains basically unchanged with the yield strength of the composite material being increased by 51.67%,the tensile strength by 75.93%and the elongation being decreased by 54.19%.
