Manufacture of squeeze cast and spray formed Al MMCs

Journal article

Squeeze casting and spray forming are relatively new processing routes for the manufacture of discontinuous fibre and particulate reinforced Al based metal matrix composites (MMCs). Both processes require the mixing of the discontinuous ceramic phase with the metallic matrix phase while the matrix is molten. In each case, ceramic/metal reactions and porosity must be minimised and homogeneous reinforcement and process repeatability maintained. This paper describes the principles of squeeze casting and spray forming of MMCs, the use of numerical simulation in process optimisation, the characteristic defects and microstructures of each process, and potential Al MMC applications.
