چکیده
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 ºC) for 4 h cooled furnace (27 ºC). studied by carrying out L27 orthogonal array experiments. Three process parameters selected, such as 0.2 mm/min depth cut, 0.1 feed rate, 1500 rpm spindle speed. obtained results indicate that surface roughness machining force MMCs increase an in weight percentage Al2O3/SiC decrease temperature. Optimum 2% + 3 180°C

متن کاملHigh Thermal Conductivity SiC/SiC Composites for Fusion Applications
SiC-SiC composites offer excellent potential for fusion energy as well as numerous commercial applications. High manufacturing cost and very low through-the-thickness (transverse) thermal conductivity (below 15 W/mK) hinders wider applications of SiC/SiC composites. To overcome these obstacles, a low-cost, Chemical Vapor Reaction (CVR) process was developed to fabricate crystalline, high purity...
