Abstract

The present study discusses the microstructure properties of Al-SiC composites. Certain deformation processes such as reciprocating extrusion (RE) were found to be applicable to strengthen the metal matrix composites (MMCs) and to refine the grains of the matrix. In line with this argument, reciprocating extrusions were implemented by applying up to five passes. The RE process was employed in fabricating a homogenous dispersion of SiCp and a fine-grain composite structure. The composites in question were studied in terms of their behaviors and microstructures on the basis of the RE process.
