摘要
为获得轻质高强度铝合金,通过真空液相吸铸工艺将304不锈钢/TiNi纤维分别嵌入到ZL105A铝合金内部,制备出高性能的纤维增强ZL105A铝基复合材料。通过试验,观察纤维表面镀铜状态对接合界面的影响,探究不同纤维种类、直径对ZL105A铝基复合材料的微观组织、力学性能及电学性能的影响规律。结果表明:纤维表面镀铜可改善纤维与基体的润湿性,提高了复合材料的综合性能;TiNi纤维增强复合材料的力学性能高于304不锈钢纤维增强复合材料;但就复合材料的电阻率来看,304不锈钢纤维增强复合材料的增强效果要高于TiNi纤维增强复合材料;在一定范围内,随金属纤维直径的增加,纤维增强ZL105A铝基复合材料的增强效果不断加强。
In order to obtain a lightweight,high-strength aluminum alloy,304 stainless steel/TiNi fiber was embedded into the ZL105A alloy through a vacuum liquid phase suction casting process to prepare a high-performance fiber-reinforced ZL105A aluminum-based composite material.The effect of different fiber types and diameters on the microstructure and mechanical properties and electrical properties of ZL105A aluminum-based composite material was investigated by observing the effect of copper plating on the fiber surface on the bonding interface.The results show that copper plating on the fiber surface can improve the wettability between the fiber and the matrix,and improve the comprehensive properties of the composite material;the mechanical properties of the TiNi fiber reinforced composite material are higher than those of the 304 stainless steel fiber reinforced composite material;it can be seen that the reinforcing effect of 304 stainless steel fiber reinforced composite material is higher than that of TiNi fiber reinforced composite material;within a certain range,as the metal fiber diameter increases,the reinforcing effect of fiber reinforced ZL105A aluminum-based composite material increases continuously.
