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...

Closed-cell A356 aluminum alloy foams refined and modified were successfully fabricated by using barite calcium carbonate as thickening foaming agents, respectively. A melt treatment consisting of adding master alloys Al-5Ti-1B Al-10Sr for refining the dendritic microstructure modifying primary eutectic silicon, respectively, included in process. The mechanical properties manufactured analyzed ...

This paper presents an experimental design approach to the process parameter optimization for compocasting of A356-SiCp composites. Toward this end, parameters of stirring temperature, stirring time, stirring speed and SiC content were chosen and three levels of these parameters were considered. The D-optimal design of experiment (DODE) was employed for experimental design and analysis of resul...
