摘要	In this study, the effect of solution temperature on artificial aging kinetics of 15 vol.% SiC particles reinforced 2009Al (SiC(p)/2009Al) composite prepared using a powder metallurgy method was investigated by means of microstructural examinations, hardness measurement and DSC analyses. The study indicated that, with increasing the solution temperature from 495 to 560 degrees C, while the GP zone formation and dissolution were retarded due to the decreased quenched-in vacancy concentration, the S' precipitation was promoted due to the increased dislocation density. This accelerated the aging kinetics of the composite with increasing the solution temperature from 495 to 560 degrees C. Furthermore, the composite which was solutionized at 530 degrees C exhibited the highest peak hardness and tensile strength. The effect of the solution temperature on the aging behavior and tensile properties of the composite was explained in terms of the variation of the microstructual mechanisms. (C) 2010 Elsevier B.V.
