    New Research Tendency of Manufacturing Technology of High Formability and High Strength Steel Tube

    • 摘要: 隨著鋼管二次成型技術(shù)的不斷發(fā)展,以鋼管為原料制造的輕體構(gòu)件因具有質(zhì)量輕、剛度好、節(jié)材節(jié)能等特點(diǎn),已被廣泛應(yīng)用于汽車、航天器及飛機(jī)制造等領(lǐng)域。隨著管材二次成型技術(shù)對鋼材強(qiáng)度和成型性能要求的不斷提高,對開發(fā)具有更高強(qiáng)度和成型性能鋼管的制造技術(shù)已引起廣泛關(guān)注。綜述了具有較高成型性能的雙相鋼管和TRIP鋼管的新型制造工藝,并詳細(xì)介紹了作者在開發(fā)TRIP鋼管中的部分研究成果。

       

      Abstract: With the rapid development of the steel tube secondary forming technology, various kinds of lightweight components manufactured from steel tubes are widely used in the automotive, space-craft and aircraft manufacturing industries due to their advantages such as being lightweight, good rigidity, saving of energy and lower material consumption and so on.Along with increasingly stringent requirements for the strength and formability of the steel products by the secondary forming process, the manufacturing technology of the tube with higher strength and better formability has drawn so much attention.Summarized in this paper are the novel manufacturing technologies of the dual phase steel tube and TRIP steel tubes with higher formability.And part of the achievements in developing the TRIP steel tube as made by the co-authors is detailed.
