Metal Matrix Composites Fabricated by Stir Casting Process–A Review

Abstract

This paper presents a detailed review of the fabrication of metal matrix composites through the stir-casting process and its processing issues. Metal matrix composites are prevalent materials among researchers and industries owing to their specific properties. These materials also offer the scope of tailoring the desired properties. There are several applications where metal matrix composites are superior to other conventional metal and alloys. However, it is evident that each type of manufacturing or fabrication process faces inherent problems and issues. The difference in properties of each constituent material such as density, melting point, strength, and severity of plastic deformation poses limitations to each processing method, either stir casting or powder metallurgy. This study attempts to reveal such processing issues of metal matrix composites by stir-casting processes.
