Al_2O_3·SiO_2/ZL109 金属基复合材料的强度性能研究

STUDY ON THE STRENGTH BEHAVIOR OF Al_2O_3·SiO_2/ZL109 METALMATRIX COMPOSITE

介绍了硅酸铝短纤维增强ＺＬ１０９铸铝合金（Ａｌ２Ｏ３ＳｉＯ２／ＺＬ１０９ＭＭＣ）的静态实验和冲击实验结果。给出了这种复合材料的静态强度、动态屈服强度和层裂强度并对实验结果进行了分析讨论。

Short fiber or particulate reinforced MetalMatrix Composites (MMC) are a class of advanced materials.These composites have extensive potential for use in aerospace and automotive industries due to their lower densities and superior mechanical properties.It is imperative therefore to study the strength behavior of such MMC.In this paper,we describe the results of quasistatic tensile and compression test,or of plate impact experiments conduced on a Al2O3·SiO2 short fiber reinforced ZL109 cast aluminum alloy.The tensile strength,compressive yield strength,dynamic yield and spall strength are presented.Discussion of the mechanical characterization of the Composite is given.
