The effects of hot rolling on the microstructure and properties of CNTs/Al composites fabricated by friction stir processing (FSP) were investigated.The results indicated that hot rolling was beneficial to the orientation of CNTs,and Al4 C3 phase was formed in the interface of CNTs/Al.The matrix grain was elongated along the rolling direction at the same time.The tensile strength and electrical conductivity of the composites were significantly improved,and the coefficient of thermal expansion was reduced along the rolling direction,attributed to the changes in the orientation of CNTs and the enhancement of interfacial binding force caused by the interfacial reaction.%在搅拌摩擦加工制备碳纳米管增强铝基复合材料(CNTs/Al)的基础上,研究了热轧对复合材料微结构与性能的影响.结果表明,热轧使基体晶粒沿轧制方向拉长,同时有利于CNTs的取向并在一些CNTs-Al界面形成Al4 C3相;基于CNTs取向等微结构的变化以及界面反应引起界面结合力增强的因素,沿轧制方向复合材料的抗拉强度、导电性明显提高,热膨胀率降低.
