摘要

使用Cu、Ni纯金属箔厚度为0.01 mm，Zr纯金属箔厚度分别为0.01 mm、0.02 mm和0.03 mm的ZrCuNi中间层在880 ℃×30 min工艺条件下对TA2纯钛进行瞬间液相焊连接试验，研究了接头界面组织演化机理、中间层元素扩散作用及接头的力学性能。结果表明，接头界面组织由焊缝中心化合物层和两侧共析组织构成，在中间层Zr箔厚度为0.01 mm时，焊缝中心形成了厚度约10 μm的连续带状（Ti，Zr）,2,（Cu，Ni）金属间化合物，当Zr箔厚度提高到0.02 mm、0.03 mm时，焊缝中心形成含有（Ti，Zr）,2,（Cu，Ni）化合物的共晶组织，共晶组织厚度先增加到80 μm后降低到37 μm。焊缝中（Ti，Zr）,2,（Cu，Ni）化合物层维氏硬度在500 HV0.1以上，其厚度减小有助于提高接头强度，中间层Zr箔为0.01 mm时接头的剪切强度最高，平均值为207 MPa，裂纹沿焊缝中心化合物层和两侧共析组织扩展，断口具有韧窝特征和河流状花样，为韧性-脆性复合断裂模式，Zr箔厚度提高到0.02 mm、0.03 mm时，接头剪切强度分别为92 MPa和135 MPa，裂纹沿焊缝中心共晶组织扩展延伸，断口形貌显示的小平面解理特征是（Ti，Zr）,2,（Cu，Ni）化合物断口的典型形貌。

Abstract

Transient liquid phase bonding was performed on TA2 titanium at 880 ℃ × 30 min using ZrCuNi interlayer with 0.01 mm Cu foil, 0.01mm Ni foil, 0.01 mm, 0.02 mm and 0.03 mm Zr foil. The mechanism of interfacial microstructure evolution, interlayer element diffusion and mechanical properties of the joint were studied. The results show that the interface structure of the joint is composed of the intermetallic compound (IMC) layer in the center and the eutectoid structure on both sides. A continuous band of (Ti, Zr),2,(Cu, Ni) IMC with a thickness of about 10 μm is formed in the jonint center with 0.01 mm Zr interlayer. When the thickness of Zr interlayer increases to 0.02 mm and 0.03 mm, the eutectic structure containing (Ti, Zr),2,(Cu, Ni) IMC is formed in the joint, and the thickness of the eutectic increases to 80 μm and then decreases to 37 μm. The microhardness of (Ti, Zr),2,(Cu, Ni) IMC is above 500 HV0.1, which thickness decreasing is helpful to improve the joint strength. The decrease of the thickness of the brittle (Ti, Zr),2,(Cu, Ni) is helpful to improve the joint strength. The shear strength of the joint is the highest with 0.01 mm Zr interlayer, and the mean value is 207 MPa. The cracks spread along the IMC layer and the eutectoid structure on both sides. The fracture features dimple and fluvial pattern, which is a composite fracture mode of toughness and brittleness. The shear strength of the joint is respectively 92 MPa and 135 MPa when the thickness of Zr interlayer increase to 0.02 mm and 0.03 mm. The crack extends along the eutectic structure, and the facet cleavage characteristics shown by the fracture morphology are typical of (Ti, Zr),2,(Cu, Ni) IMC.
