Aluminum/alumina composites are used in automotive and aerospace industries due to their low density and good mechanical strength. In this research, the effect of mechanical stirring of slurry in liquid-solid phase temperature and injection of alumina powder with inert gas (Ar) on microstructure and mechanical properties of Al-A356 alloy is investigated. In order to improve of the wettability a...

Abstract Compo-casting method is one of the popular techniques to produce metal-based matrix composites. But main challenges in this process un-uniform spreading reinforced subdivisions (particles) inside metallic and lack desirable mechanical properties final produced composites due low bonding strength among metal reinforcement particles. To remove these difficulties promote kind composites, ...

One of the popular techniques to fabricate metal matrix composites is compo-casting process. The un-uniform spreading reinforced subdivisions (particles) inside metallic and lack desirable mechanical properties final produced due low bonding strength among reinforcement particles are main challenges in this warm accumulative press (APB) technique was utilized as supplementary improve microstruc...

In this study, metal matrix-based composite (MMC) was subjected to Equal Chanel Angular Pressing (ECAP) in several passes determine the influence of deformation on hardness samples. Composite based A356 aluminum alloy and reinforced with Fly Ash (FA) particles obtained by compo casting method. The microstructural analyses microhardness measurements were performed cast pressed Vickers measuremen...
