| Abstract Scope |
Friction stir processing (FSP) has proved to be successful in the past two decades for the preparation of novel metal matrix composites with preferable properties. In this work, graphite was added into 6201 aluminum alloy through multi-pass in-situ FSP in order to fabricate graphite-reinforced 6201 aluminum alloy. We look into the microstructure, the mechanical and electrical properties of the composites. It is found that, after multi-pass FSP, the graphite is significantly fragmented and uniformly distributed in the aluminum matrix. The tensile strength and electrical conductivity of the composites with 9-pass FSP are improved by 19.5% and 1.2% in comparison to the matrix. The number of FSP passes is an important parameter affecting the microstructure of the composites. Effect of the number of FSP passes on the tensile strength and electrical conductivity of the composites is investigated. |
