摘要：
The tensile behaviour of nanometric SiC particulate (SiCp) reinforced aluminium, matrix composites (AMCs) was examined at room temperature, 215 degrees C and 350 degrees C. These AMCs were produced via powder metallurgy (P/M) using Al 7075 powder reinforced with different volume fractions (1 vol.%, 3 vol.% and 5 vol.%) of nano-SiCp. The experimental results exhibit that at room temperature un-reinforced Al has both maximum strength and ductility whereas the 5 vol.% SiCp/Al composite has only maximum stiffness. Similar trends were obtained for tests performed at 215 degrees C. However at 350 degrees C, the 1 vol.% SiCp/Al composite has the highest stiffness. Optical microscopy and scanning electron microscopy were performed for microstructure study, examination of the SiCp distribution in the Al matrix and fractography.
