The effects of solution (quench) temperature on the properties of SiCw/Al composite have been investigated using tensile tests. The experiments indicate that the solution temperature of the composite fabricated by P/M technique can be raised to 560℃. The tensile strength of the composite is obviously dependent on solution (quench) temperature and the composite solutionized at 540℃ exhibits a maximum of tensile strength and elongation-to-failure. These results can be accounted for by the variation of the dislocation density in the composite.
