中文摘要：综述了超低碳贝氏体钢及其焊接性的国内外研究现状，总结了各种合金元素对超低碳贝氏体钢相变作用和工艺制备方法，并就其对焊接性的影响进行了分析。对超低碳贝氏体钢焊接材料的选取和新型焊接材料的开发所面临的问题进行了讨论。
英文摘要：The recent research and development of ultra low carbon bainite (ULCB) steels in China and abroad were reviewed. The effects of alloying elements on thermo-mechanically processed bainite steels and weldability of the steels were examined. The encountered problems in the selection of welding materials and the development of new types of welding materials for ULCB steels were also discussed.
