摘要
钛-钢复合材料兼具钛的耐腐蚀和钢的高强度、低成本等优点，是一种用途广泛的复合材料，在压力容器、石化和能源等领域具有非常强的竞争力。主要的钛-钢复合材料制备方法：爆炸焊接法、爆炸＋轧制法和轧制法。主要介绍这3种方法，综述了国内外对这3种工艺的研究现状，概述了各种工艺对应的钛-钢复合材料的力学性能与界面结合情况。这几种方法都可能涉及到热处理，尤其是热轧法。热作用对其影响较大，因此本文借鉴较多热扩散的观点对其进行表述。综合已有的研究，发现钛-钢复合的界面脆性相问题是影响其力学性能的主要原因。如何减少和抑制界面脆性相的生成，如何提高界面力学性能，是目前钛．钢复合材料的研究重点。
Titanium-steel composite materials had the advantages of corrosion resistance of titanium and high strength and low cost of steel. It was a kind of widely used composite material, which was very competitive in pressure vessel, petrochemical and energy fields. Explosive welding, post-explosion rolling and rolling were the main titanium-steel composite plate manufacturing methods. This paper mainly introduced the three methods, summarizing the research status of these three processes at home and abroad, and the mechanical properties and interface of titanium steel composites corresponding to the three processes. These methods might include heat treatment, especially hot rolling. Hot rolling was described from the viewpoint of thermal diffusion. Based on the existing research, it was found that the interfacial brittle phase problem of titanium-steel composite was the main reason for its mechanical properties. At present, the research focus of titanium-steel composites was how to reduce and inhibit the formation of interfacial brittle phase and how to improve the interface mechanical properties.
