中文摘要：

对TA1／Q235钢复合板累积叠轧焊进行了研究．研究结果表明：采用累积叠轧焊方法能够制备出结合性能较好的钛／碳钢复合板，其结合强度随着累积变形量与首道次变形量的增加而提高，叠轧过程中经磨床打磨与喷丸处理获得洁净、新鲜并具有一定加工硬化程度的结合界面，会促进复合板结合强度的提高．800℃以下热轧后，Q235钢的组织呈明显的条带状；而850℃以上热轧后。Q235钢条带状变形组织逐渐转化为等轴状，界面附近的Q235钢脱碳，出现明显的排列整齐且粗大的铁素体晶粒带．钛侧的组织主要有等轴α组织和魏氏α组织．综合考虑轧制温度对钛与Q235钢组织与界面结合性能的影响，累积叠轧温度应控制在800～850℃之间．

英文摘要：

A manufacturing process bas titanium ed on the accumulative roll-bonding （ARB） technology for TA1/Q235 clad plates was demonstrated. It is found that well-bonded clad plates can be obtained by this process. The bond strength improves as the accumulative deformation and the first pass deformation increase. The surface treatment methods, i.e. rotoblasting and grinding help get a clean, fresh and work-hardening interface, therefore improve the bond strength of TA1/Q235 clad plates. When the rolling temperature is lower than 800℃, the stripped microstructure of Q235 steel can be examined. However, when rolling temperature is higher than 850℃, this kind of stripped microstructure turns into equiaxed grains due to recrystallization. In addition, there are ferrite belts with regular and coarse grains along the joint interface, but the microstructure of TA1 titanium is mainly equiaxed α and Widmannstatten α structures in metallographic analysis. Considering the microstructures of Q235 steel and TA1 titanium and their bonding properties, the ARB temperature should be controlled in the range of 800 to 850℃.
