Mechanical and Microstructure Properties of Al and SiC Reinforced Aluminum-Based Metal Matrix Composite
Abstract: It is becoming increasingly difficult to design new technical materials that are resistant to wear damage and corrosion degradation in severe service circumstances. Unfortunately, even with crucial passive metals, like Al alloys, there is often a compromise between wear and corrosion resistance. Because of the unfavorable galvanic connection between the precipitates and the matrix, precipitates not only harden the material but also accelerate corrosion. This research established that a supersaturated …
