与带夹层的Cu/Al接头相比，带夹层的Al/Cu接头焊接界面发生了更高的温度和更严重的塑性变形。对于这两个接头，垂直于铝板厚度方向的硬度与原始硬度相比都有明显的变化。带夹层的Al/Cu接头的峰值搭接剪切拉伸强度（78.3 MPa）比带夹层的Cu/Al接头（61.5 MPa）高27.3%。 (C) 2017 Elsevier B.V. 保留所有权利。
Higher temperature and more severe plastic deformations took place in the weld interface of Al/Cu joint with interlayer compared with that of Cu/AI joint with interlayer. For the both joints, the hardness perpendicular to the thickness direction of the aluminum sheet has a significant change compared with the original hardness. Peak lap shear tensile strength of Al/Cu joint with interlayer (78.3 MPa) is 27.3% higher than that of Cu/AI joint with interlayer (61.5 MPa). (C) 2017 Elsevier B.V. All rights reserved.
