- 摘要:
- 汽车轻量化为高锰TWIP钢带来了广阔的开发和应用前景。 TWIP钢从1997年被开发出来到现在已经发 展了3代,在这20多年的时间里有大量的研究者对其力学性能、微观组织及加工工艺进行了广泛的研究。 本文综述了 汽车用高锰TWIP钢研究现状及进展,介绍了TWIP钢的发展历程与影响TWIP效应的因素,同时对微合金化及不同应 变速率对TWIP钢组织和性能的影响的研究现状进行了概述;总结了国内外相关研究取得的成果,也指出了有待进一 步研究的内容,为以后研究方向提出相关建议。Automotive lightweight had brought broad development and application prospects for high manganese TWIP steel. TWIP steel had developed for three generations since it was discovered in 1997. In the past 20 years, a large number of researchers had conducted extensive studies on its mechanical properties, microstructure and processing technology. The development of TWIP steel and the factors affecting TWIP effect were introduced, and the effects of microalloying and different strain rates on the microstructure and properties of TWIP steel were summarized. The achievements of relevant researches at home and abroad is summarized, and points out the contents to be further research direction.
