| Abstract: | In this paper the solid-state composite concept was proposed.The pre-composition process of SiC particle and pure Al powder, the secondary composite process of pre-composition block and poor aluminium A17090 alloy liquid, the composite slurry diecasting process were investigated by using two-step composite method.The φsic=10% SiCp/7090A1 composite had been produced successfully.The results showed that the SiC particle distributed uniformly in the composite matrix and the SiC particles and a good combination with matrix alloy. |
