Interfacial characteristics in metal matrix composites reinforced with ceramic reinforcements (MMCs) play a significant role in determining the mechanical properties, such as strength, ductility, toughness, fatigue, etc. To achieve superior mechanical properties in MMCs, it is essential to form adequate interfaces, which not only do not degrade the reinforcement during fabrication, but also retain the structural stability both for corrosive environments and at elevated temperatures. The objective addressed in the present work is to study a methodology to control the interfacial microstructures in the SiC/Al composite. Assessment of the stability of the newly formed interface at elevated temperatures was also made.
