我们重点介绍强相变诱导塑性 (TRIP) 钢的最新进展，与传统 TRIP 钢相比，该钢具有更高的合金含量，可实现高于 1 GPa 的拉伸强度。鉴于非凡的强度-伸长率平衡是由粗粒和亚微米尺寸的铁素体和奥氏体晶粒的特征混合物导致的，因此对获得前所未有的性能的材料设计的多种策略进行了回顾。还讨论了实现拉伸性能以外的重要工程参数的挑战，应解决这些挑战，以确保相对于其他新兴结构替代方案的竞争力。 (C) 2016 Acta Materialia Inc. 由 Elsevier Ltd 出版。保留所有权利。
We highlight the recent advance in strong transformation-induced plasticity (TRIP) steels, which have higher alloying contents compared to the conventional TRIP steels for achieving tensile strength higher than 1 GPa. Given that the extraordinary strength-elongation balance is led by the characteristic mixture of coarse and sub micron-sized grains of ferrite and austenite, diverse strategies of materials design to obtain unprecedented properties are reviewed. Challenges to achieve the vital engineering parameters other than tensile properties are discussed as well, which should be resolved to secure competitiveness over other emerging structural alternatives.
