【Abstract】 Solution hardening and aging treatment was applied to SiC p/Al composite with high SiC p particles content and its influence on the thermal conductivity and strength was evaluated It can be concluded that the heat treatment leads to the increment of the thermal conductivity through improvement of the interface bonding and the thermal conductivity factor can be high as 210 W/(m·K) The heat treatment also strengthens the Al alloy and leads to the change of the SiC p particles’ stress condition, and therefor increases the composite’s strength which can be high as 519 MPa更多还原
