| Abstract Scope |
Bulk metal matrix composites (MMCs) can be produced by stir and filtration casting or solid-state deposition and sintering. The microstructures of the MMCs produced, especially the by casting methods, have various shortcomings, including particle segregation, coarse matrix grains or dendrites, and low high fraction of the ceramic particles. Recently, an emerging approach based on friction stir additive manufacturing (FSAM) for fabricating bulk aluminium (Al) alloy MMCs has demonstrated potentials to overcome the microstructural shortcomings.
This study focuses on microstructural characterization and mechanical testing of these bulk Al alloy MMCs that are formed by FSAM. Microstructures of these Al alloy MMCs are examined in terms of the size, fraction and distribution of the added particles and the refinement of the Al phase in the matrix. The characteristics of the microstructures is correlated with significant improvement of hardness and mechanical properties of the bulk Al alloy MMCs. |
