Fabrication of Metal Matrix Composites by Friction Stir Processing

Abstract

Friction stir processing (FSP) is gaining wide attention as an alternative route for the fabrication of metal matrix composites. This chapter commences with a general introduction to various aspects of metal matrix composites and various processing routes for their fabrication. It then provides basics of friction stir processing and briefs about multiple methods of secondary phase/reinforcement incorporation in the matrix. In the subsequent section, the effect of different FSP parameters on the mechanical properties and wear behavior of the composite material are discussed in detail. The chapter finally presents the summary of the significant aspects of composite fabrication by FSP and scope for future work.
