摘要
用金相、Ｘ光、电子探针和透射电镜等方法对铜铝冷轧固相复合烧结后界面组成的形貌与结构进行了研究。确认存在γ_２、δ、ζ_２、η_２、θ等五种中间相，尺寸分别在１０^（－４）、１０^（－５）、１０^（－５）、１０^（－９）和１０^（－７）ｍｍ~２量级；在形态上γ_２、σ、ζ_２均呈多边形块状，只是前者较后者为大，且γ_２内有许多平行板条，θ相近似卵形，η_２为弥散颗粒、迹象表明分布具织构向，η_２的织构可能是（１００）［０１１］。
The microstructure of diffusion layer was investigated after cold-rolling bonding and sintering for the copper-aluminum strips by metalloscope, XRD, TEM, EPM, etc. It is confirmed that there are five intermediate phases, γ_2,δ,ζ_2, η_2, and θ. The size of these intermediate phases are relatively small and respectively at the quanlity grade of 10￣(-4) , 10￣(-5), 10￣(-5) , 10￣9 and 10￣(-7) mm￣2. The morphology of γ_2,δ,ζ_2 is like-polygonal lump, but the size of γ_2 is the largest and ζ_2 is the smallest among the three phases, also there are a lot of parallel laths in the γ_2. The form of θ phase is similar to ovoid and that of η_2 phase is dispersive grain. Some evidences show that the distribution of some of the intermediate phases appeared as tendency to texture. It is possible that the texture of η_2 phase is (100)[011].
