| Abstract: | Based on the traditional power metallurgy technique, Si particle reinforced Al matrix composite was fabricated by adding zinc on Al and Si powder block during sintering. The microstructure and mechanical properties was investigated by varying process parameters such as power blending technique, pressure, sintering atmosphere, sintering temperature. The microstructure was observed and analyzed through optical microscope and SEM. The zinc added sintered composite product were studied and compared with the Al and Si powder sintered product without zinc. |
