以体积分数为60%的SiC颗粒增强铝合金复合材料为研究对象,利用实验方法研究了该材料的宏观力学特性,通过ANSYS仿真软件模拟了微缺陷对材料力学性能的影响。研究表明,界面脱粘是影响高体积分数合金复合材料拉伸应力—应变曲线呈现非线性的重要原因,能够影响材料承载性能。为不同体积分数的颗粒增强金属基复合材料铸造工艺的优化提供了参考依据。
The macroscopic mechanical properties of the SiC particle reinforced aluminum alloy composite with 60% SiC particle size were studied. The mechanical properties of the material were simulated by ANSYS simulation software. The results show that the interfacial debonding is an important factor that influences the nonlinearity of the tensile stress-strain curve of high volume fraction alloy composites, which can affect the material bearing capacity. It provides a reference for optimizing the casting process of particle reinforced metal matrix composites with different volume fraction.
