| 中文摘要: |
| 本文通过剪切强度测试、剪切断面显微观察和有限元仿真等手段对不同Cu/Al层厚比下波纹辊轧制（CRB）Cu/Al复合板的金属的变形行为和界面结合性能进行了研究。结果发现，CRB过程中界面处形成了局部强正应力和多个“搓轧区”，促进了复合板的塑性变形和界面结合。增大Cu/Al层厚比可提升Cu层的变形率和波谷界面处的正应力，有利于降低Cu/Al复合板的翘曲程度，并增强界面的整体结合性能。当层厚比从2:10增加到2:4时，界面剪切强度从40.39 MPa上升到47.24 MPa，但界面剪切强度的波动逐渐增大。 |

| 英文摘要: |
| The deformation behavior and interfacial bonding properties of Cu/Al clad plates with different Cu/Al thickness-ratio by corrugated roll bonding (CRB) were investigated by shear strength test, microstructure observation of shear section and finite element simulation. The results show that increasing the Cu/Al thickness-ratio is beneficial to reduce the warpage of the Cu/Al clad plates and improve the overall bonding properties of the interface. When the Cu/Al thickness-ratio is 2:4, the Cu/Al clad plate hardly warps, and the shear strength reaches 47.24 MPa. As the Cu/Al thickness-ratio decreases, the rolling deformation zone expands and the rolling force is dispersed. Thus, the peak value of normal stress and average shear strength at the interface both decrease gradually. The shear stress generated by multiple "cross-shear" zones and the local strong normal stress formed at the interfaces during the CRB process significantly promote the plastic deformation and interface bonding of the clad plates. |
