摘　　要：为提升铜/铝复合材料的综合性能,简化生产工艺流程,以纯铜(T2)和铝合金(2A12)为原材料,采用爆炸复合法成功制备了T2/2A12棒状复合材料,研究了T2/2A12复合材料的界面组织、力学性能和导电性能。结果表明:T2/2A12复合材料结合界面宏观为介于平直界面和波状结合界面之间的形态,微观上形成了约7μm的扩散层,实现了良好的冶金结合。T2/2A12爆炸复合材料的剪切强度为96.5 MPa,抗拉强度为551 MPa,伸长率为17%,导电率为67%IACS;结合界面至基体的显微硬度分布较为均匀,靠近界面处因加工硬化作用硬度略高于基体。In order to improve the comprehensive properties and simplify the production process,pure copper(T2)and aluminum alloy(2A12)were used as raw materials,and high-performance T2/2A12 rod composites were successfully prepared by explosive compounding.The interface structure,mechanical properties and electrical conductivity of T2/2A12 composites were studied.The results show that the bonding interface of T2/2A12 composite was between flat interface and wavy interface,and a diffusion layer of about 7μm was formed,which achieved good metallurgical bonding.The results show that the tensile strength of the T2/2A12 composite in the explosive state is 96.5 MPa,the shear strength is 551 MPa,the elongation rate of 17%,and conductivity of 67%.The microhardness distribution from the bonding interface to the matrix is uniform,and the hardness near the interface is slightly higher than that of the matrix due to work hardening.
