In the present research, effects of volume fraction SiC+Al2O3 particles and aging temperature on machinability stir-casted Al7075 metal matrix composites (MMC) have been investigated. The hybrid were fabricated using liquid metallurgy route. was reinforced with different wt. % SiC (3%, 6%, 9%) Al2O3 (2%, 4%, 6%) which used to fabricate composites. samples aged at temperatures (140 ºC, 160 180 º...

Silicon Carbide (SiC) is believed to be a revolutionary semiconductor material for power devices of the future; many SiC power devices have emerged as superior alternative power switch technology, especially in harsh environments with high temperature or high electric field. In this chapter, the challenges and recent develop‐ ments of SiC power devices are discussed. The first part is focused o...

The paper attempts to study the machinability issues of aluminium-silicon carbide (Al-SiC) metal matrix composites (MMC) in turning using HSS cutting tool. SiCp-reinforced metal matrix composites (MMCs) containing SiC particles (5wt%-20wt %) of 400mesh size were prepared by powder metallurgy (P/M) route and used as work material for turning. Experiments were conducted at various cutting speeds ...

In the advancement of directed energy deposition, 3D printing technology has been undergoing revolutionary changes, especially in metal and polymer technology. On contrary, ceramics not experienced such rapid development due to their requirement for high-temperature sintering inferior adsorption property, limiting use application as direct selective laser (SLS). this study, a novel controlled f...
