The results show that, Au-19.25Ag-12.80Ge brazing alloy is better, its melting temperature range is 446.76494.40 ℃, and the temperature interval between the solidus and the liquidus is 47.64 ℃. When the brazing temperature is in the range of 510550 ℃, the alloy has a good spreadability and wettability with Ni. Interface structure observation reveals that there is one continuous intermetallic layer between the brazing alloy and the base metal Ni when welding. X-ray energy spectrum analysis results show that the intermetallic layer is Ge3Ni5, and because of its brittleness, the overthick intermetallic layer will decrease the shear strength of the welding joint, therefore, the welding technology should be controlled so as to gain an ideal welding interface structure.

研究结果表明：Au-19.25Ag-12.80Ge合金的性能较好，其熔化温度范围为446.76~494.40 ℃，结晶温度区间为47.64 ℃；焊接温度在510~550 ℃范围内时，Au-19.25Ag-12.80Ge钎料合金与Ni基体具有良好的铺展性和润湿性，焊接时钎料合金与Ni基体之间形成了一条连续的金属间化合物层，能谱分析表明该金属间化合物层为Ge3Ni5，由于该化合物较脆，过厚的金属间化合物层使焊接接头的剪切强度下降，故应适当控制焊接工艺以获得理想的焊接界面组织。

Thirdly, with the modified Gurson model of the MARC finite element method soft, the damage behave of the welded joint was simulated. It was found that in the undermatched welded joint, the damage mainly happened in the soft weld line and with the decrease of the weld line抯 width, the damage抯 development was faster. As for the overmatched welded joint, the results showed that the damage mainly happened in the soft base metal and with the increase of the weld line抯 width, the damage抯 development was faster. While the width of the weld line was narrower than three millimeters, the high strength weld line could improve the anti-damage capability of the overmatched welded joint.

通过计算发现在低匹配的焊接接头中，损伤主要发生在低强度的焊缝中，并且焊缝宽度越小，焊接接头的损伤就越严重；而在高匹配的焊接接头中，损伤主要发生在紧临焊缝的强度较低的母材上，随高强度焊缝宽度的增加，焊接接头的损伤发展程度加剧，当焊缝宽度小于3mm时，高强度焊缝的加入对焊接接头能起一个强化的作用，提高了焊接接头的抗损伤能力。
