摘　　要：研究了T6热处理对6066Al/SiCp复合材料材料力学性能的影响,结果表明,复合材料经530℃固溶1 h后,170℃时效8 h达到峰时效,其抗拉强度达418.6 MPa;复合材料延伸率随时效时间的增加不断降低.The effects of T6 treatment on mechanical properties of the 6066Al/SiCp composite were studied in this paper. The result shows that the ultimate tensile strength of the 6066Al/SiCp composite could reach 418.6 MPa when solulion treated at 530 ℃ for 1h,then aged at 170℃ for 8h; the ductility decreased with the increase tff aging time.
