摘　　要：钛铝复合板兼具钛和铝合金各自的优点,广泛应用于多个工业领域。轧制法是目前制备钛铝复合板最成熟的方法。介绍了轧制法制备钛铝复合板涉及的基本理论以及影响界面结合强度的因素,对目前钛铝复合板结合强度检测方法进行了总结,以期为钛铝复合板的制备提供较为全面的指导。分析认为:钛/铝复合板要实现良好的界面结合,其变形率要大于阈值,阈值的具体数值随轧制方法的不同而变化。波纹辊轧制、叠层累积轧制等轧制方法在相同的压下量条件下,界面结合强度高于普通平轧;轧后热处理会生成一定厚度的界面层,界面层主要为TiAl_(3)金属间化合物,并且界面层的厚度需要控制在合理范围之内;钛铝复合板层的层数越多,界面起伏越明显,有利于界面结合强度的提高。Ti/Al clad plates combine the advantages of titanium and aluminum and have been widely used in various industrial fields. Rolling technique has been well established for processing Ti/Al clad plate. The basic theory involved in rolling technique and the factors affecting the interface bonding strength of Ti/Al clad plates are briefly introduced in this paper. Then the test methods for bonding strength of Ti/Al clads are summarized. This paper intends to provide a theoretical basis for obtaining high-quality Ti/Al clad plates. Enabling Ti/Al clad plates excellent interface bonding performance, the applied reduction ratio shall excess a certain threshold depending on the rolling method. With the same rolling reduction ratio, the new rolling techniques such as corrugated rolling and accumulative rolling perform higher interface bonding strength than conventional rolling. Diffusion layers appear at the bonding zones subject to heat treatment after rolling, and the main metallic compound is TiAl_(3). And the thickness of diffusion layers must be controlled in reasonable limits. The wavy morphology of Ti/Al interface becomes obvious with the increased layers and this is beneficial to improve interface bonding strength.
