针对ＣｕＡｌＢｅ 合金与不锈钢扩散连接，研究了扩散焊工艺参数对接头变形率的影响以及接头的变形率与接头强度的关系。研究结果表明：随温度、压力和时间增加，ＣｕＡｌＢｅ 合金变形率迅速增加，而１Ｃｒ１８Ｎｉ９Ｔｉ 变形率较小；随变形率增加，界面紧密接触，接头强度增加；当变形率较小时界面有未焊合存在。液相扩散焊时，随变形率增加，接头强度增加 According to the diffusion bonding between CuAlBe alloy and stainless steel, the effect of technological parameters of diffusion welding on the deformation ratio of the joint and the relationship between the deformation rate of the joint and the strength of the joint were studied. The results show that the deformation rate of CuAlBe alloy increases rapidly with the increase of temperature, pressure and time, while the deformation rate of 1Cr18Ni9Ti is small. With the increase of deformation rate, the interface is in close contact and the joint strength is increased. When the deformation rate is small, the interface has unsoldered . Liquid phase diffusion welding, with the deformation rate increases, the joint strength increases
