摘要: 采用真空制坯轧制复合法,在相同的加热温度、轧制道次和压下量等工艺条件下,分别对钢丝刷打磨、酸洗和带水砂带机打磨的表面处理方式,研究了3组钛/钢复合板的界面组织和力学性能.分析了表面处理方式对界面结合性能的影响.结果表明:带水砂带机表面处理方式下的钛/钢复合界面生成连续均匀的TiC层,剪切断口呈韧窝状,界面剪切强度稳定,平均强度达到242.6MPa.其他两种表面处理方式下的钛/钢复合板界面生成断续的TiC层,其剪切强度均未满足国家标准.

Abstract: Under the same heating temperature, rolling pass and pressure reduction by using vacuum roll cladding(VRC),the interfacial microstructure and mechanical properties of three groups titanium/steel composite plates were studied after one of three different surface treatment methods which were wire brush grinding, pickling and polishing machine with water. The influence of surface treatment on the interfacial bonding properties was analyzed. The results showed that a uniform and continuous TiC layer is formed at the bonded interface when the surface treatment of the polishing machine with water is carried out. The fracture surfaces are full of dimples, the interfacial shear strength is stable with the average shear strength of 242.6MPa. However, the discontinuous TiC layers are formed in the interfaces of the titanium/steel plates subjected to the other two surface treatments and the shear strength of these two plates cannot meet the national standard.

Key words: vacuum rolling cladding(VRC), surface treatment, electron-beam welding, analysis of microstructure, interface bonding performance
