在开放环境下,使用氩气保护,采用Cu-Ni-Sn-P系非晶合金箔作为中间层,对TA2工业纯钛进行了不同连接温度的瞬时液相扩散焊。观察了接头界面组织形貌,分析了接头界面元素分布,测试了接头的剪切强度,并对接头进行了断口分析。结果表明:连接接头剪切强度随连接温度的升高先增加后降低,在850℃时具有最高的剪切强度,约为180 MPa,并在断口上生成了Cu Ti、Cu Ti_2等金属间化合物,且断口呈现塑性+脆性混合断裂方式。
In the open environment, the use of argon gas protection, the use of Cu-Ni-Sn-P series amorphous alloy foil as the intermediate layer, TA2 industrial pure titanium were connected at different temperatures transient liquid phase diffusion welding. The morphology of the interface of the joint was observed. The elemental distribution of the joint was analyzed, the shear strength of the joint was tested, and the fracture of the joint was analyzed. The results show that the shear strength of the joints increases firstly and then decreases with the increase of the connection temperature, and reaches the highest shear strength of about 180 MPa at 850 ℃, and intermetallic compounds such as Cu Ti and Cu Ti 2 are formed on the fracture surface , And the fracture presents plastic + brittle fracture mode.
