摘要：
The present study is focused on the evaluation of the aging behaviour and microstructure characterization of AA2124/SiC/25p composite under the aging temperatures of 180, 185 and 190 degrees C For Various dwelling time ranging from 0 up to 100 hours. The microstructure was characterized by means of scanning electron microscopy. The hardness, energy dispersive spectroscopy analysis and X-ray diffraction measurements were also performed to evaluate the characteristics of aged AA2124/SiC/25p composite. The results show that the hardness values of as-received composite were considerably improved LIP to two third by the Subsequent aging. The hardness increasing was attributed to the presence of CuAl2, Al4SiC4 and precipitation phases in aged AA2124/SiC/25p composite.
