摘要:

应用微型储能焊机实现了厚度为25---35 μm的Zr₅₅Cu₃₀Al₁₂Ni₃非晶箔材的快速凝固连接. XRD测试表明, 接头仍为非晶结构. 计算的接头冷却速率高达10⁶ K/s, 远大于形成锆基非晶合金的临界冷却速率, 有效地抑制了接头区的晶化. 接头尺寸微小, 直径为60---90 μm, 未产生气孔、夹杂等焊接缺陷. 接头剪切强度高达1141 MPa. 高的电阻率特性使非晶合金的焊接能量明显低于晶态合金.

关键词 ：锆基非晶合金, 超薄箔, 快速凝固焊接, 接头性能

Abstract：

The rapid solidification welding of Zr₅₅Cu₃₀Al₁₂Ni₃ amorphous foils with the thickness of 25---35 μm was conducted using a micro--type capacitor discharge welder. XRD analysis shows that the joint presents still amorphous structure under the rapid solidification welding conditions. The joint cooling rate calculated is high up to 10⁶ K/s, which is much higher than that of critical cooling rate of amorphous Zr base alloy, and effectively suppresses the crystallization of joint zone. The micro joints with the size of 60---90 μm in diameter are produced and there are no welding defects such as porosity and inclusions within the joints. The joint shear strength is up to 1141 MPa. Contributing to higher electrical resistivity, the welding energy for welding metal glass foils is lower than that of crystallized metal foils remarkably.

Key words： Zr base amorphous alloy ultra--thin foil rapid solidification welding mechanical property of joint
