钛/钢层合板轧制复合研究进展与展望

钛/钢层合板兼具钛的耐腐蚀性与钢的良好强度和塑性,广泛应用于海洋工程装备、水电站、核电站、核潜艇等领域。为进一步推动对钛/钢层合板的深入研究,促进钛/钢层合板的发展,对近年钛/钢层合板制备方法进行分析。分析发现轧制法作为一种经济、环保的制备方法,将会成为制备钛/钢层合板的主流工艺,因此重点讨论轧制钛/钢工艺参数、界面组织特征、界面结合机理与化合物形成机制。分析制备温度、轧制工艺、化合物种类、退火工艺等因素对钛/钢层合板力学性能的影响,发现变形不协调、温度与脆性化合物始终是影响层合板界面强度提升的重要因素。通过添加中间层可以在一定程度上改善界面成分并提高界面结合强度,而温度过高会导致严重的界面缺陷。因此,钛/钢层合板未来的研究方向与发展前景是通过轧制法制备波纹界面层合板以及将辅助能场引入层合板轧制领域。

Research progress and prospects of rolling titanium/steel laminates

Titanium/steel laminate has both the corrosion resistance of titanium and the good strength and plasticity of steel, and is widely used in marine engineering equipment, hydropower stations, nuclear power plants, nuclear submarines and other fields. In order to further promote the in-depth research on titanium/steel laminates and promote the development of titanium/steel laminates, the preparation methods of titanium/steel laminate in recent years are mainly analyzed. The analysis found that the rolling method, as an economical and environmentally friendly preparation method, will become the mainstream process for preparing titanium/steel laminates. Therefore, the process parameters, interface structure characteristics, interface bonding and compound formation mechanism of rolled titanium/steel were mainly discussed. The influence of factors such as preparation temperature, rolling process, compound type, annealing process on the mechanical properties of titanium/steel laminates were analyzed. It was found that the deformation inconsistency, temperature and brittle compounds were the important factors affecting the improvement of the interface strength of laminates. Adding an intermediate layer can improve the interface composition and the interface bonding strength to a certain extent, but when the temperature was too high, it will cause serious interface defects. Therefore, the future research direction and development prospects of titanium/steel laminates are the preparation of corrugated interface laminates by rolling and the introduction of auxiliary energy fields into the field of laminate rolling.
