| Abstract: | Combined self-propagating with casting,in-situ Al2O3 particle-reinforced copper matrix composite was fabricated.Effects of processing parameters such as the ratio of aluminum powder and copper oxide powder,reaction temperature,pressure for formation of the precast block,and time of powder mixing.The results show that the appropriate processing parameters are as follows:the ratio of aluminum powder and copper oxide powder is 2∶ 1,the copper powder addition amount accounts for 5% of the total mass,precast block forming pressure is 12 MPa,the point of pouring is 1 120 ℃,and the time of powder mixing is 30 min. |
