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...

This paper studies the milling process of SiCp/Al2024 composite with high volume fraction and large particle size. The mechanism is analyzed. influence cutting depth feed per tooth on surface quality It reveals subsurface damage workpiece. results show that in composite, because edge radius much larger than radius, main form removal crushing. defects workpiece mainly include pits, cracks, scrat...

This research paper deals with the joining of different materials such as SiCp/6063Al MMCs and Fe-Ni alloys by means of vacuum brazing with active filler metal Ag47-Cu18-In17-Sn17-Ti1. With the optimal process parameters, i.e., brazing temperature 580 °C, soaking time of 30 min and vacuum degree of 6....

Metal matrix composites are undoubtedly a group of advanced engineering materials. Compared to unreinforced matrix material, they are characterized by increased strength, greater stiffness, increased wear resistance, better mechanical properties and dimensional stability at elevated temperatures as well as lower density. Due to its very favorable tribological properties for many years research ...
