过渡材料在高能束流连接钛钢中的应用

Application of transition materials in the connection of Titanium alloys and steel by high energy beam

钛与钢的连接既能满足性能要求又能降低成本,因此钛钢焊接受到了广泛关注。鉴于它们的物理性能差异较大,直接连接的强度特别低甚至完全开裂,因此增加中间过渡材料的方法成为研究热点。高能束流特别是激光和电子束具有能量密度高和焊接熔宽窄的特点,对焊接钛钢具有一定优势。综述了高能束流连接钛钢接头时所添加的过渡材料的种类和应用情况。

The connection of titanium alloy and steel can meet the requirements of performance but also reduce the cost, so theproblem of welding titanium and steel have been widely concerned. However, due to their great differences in properties, the strengthof the direct connection is extremely low or even completely cracked, so the method of increasing intermediate transition materials hasbecome the focus of research. In addition, high energy beam especially laser and electron beam has the characteristics of high energydensity and small weld width so that welding of titanium and steel has certain advantages. In this paper, the types and application oftransitional material added when welding the joint of titanium and steel by high energy beam are reviewed.
