Industrialization of cast aluminum matrix composites (AMCCs)

This paper briefly describes the main research points and activities which have been considered toward industrialization of cast aluminum matrix composites (AMCCs). First, the issues in liquid processing of metal matrix composites are reviewed. The different requirements for successful AMCCs are then described. Post-processing such as heat treatment, forming, and machining, which can be performed on AMCCs, are discussed. The up-to-date, specially modified commercial foundry technologies that are needed for the practical production of AMCCs are briefly described. The main efforts made by some associations and industrial firms focusing on AMCCs are also summarized. Finally, examples are given for the available practical AMCCs, either in the form of raw composite ingots or shape casting.
