Abstract 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 Al₄C₃ 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.

Key words： hot rolling friction stir processing CNTs/Al composites microstructure property
