安全、节约燃料、抗表面凹陷和追求舒适是汽车行业的一大进步。其中节约能源是汽车行业钢材用户们最重要的目标之一。但是，通常对于一个给定的冶金工艺来说，抗拉强度的增加会导致延性的损失。Arcelor开发的系列高锰合金钢（被称为FeMnTWIP1000钢）正试图达到汽车行业所要求的最佳力学性能和使用性能。

D.Cornette等人通过对FeMnTWIP1000钢显微组织、变形方式、材料性能、成形性能、撞击特性、疲劳性能、可焊性的大量研究发现，这类以锰为主要合金化元素的产品拉伸应力超过1000MPa，总延伸率可提高50%，兼具良好的成形性、强度、延性和应变硬化特性，对减重、抗冲击和提高汽车撞击安全性非常有用。

Safety, fuel economy, anti-surface depression and the pursuit of comfort is a big step forward in the automotive industry. Energy conservation in the automotive industry where steel users one of the most important goals. However, usually for a given metallurgical processes, the tensile strength increase will lead to the loss of ductility. Arcelor developed a series of high manganese steel (known as FeMnTWIP1000 steel) are trying to achieve the requirements of the automotive industry the best mechanical properties and performance. D. Cornette, who by FeMnTWIP1000 steel microstructure, deformation, material properties, formability, impact properties, fatigue properties, weldability of the large number of studies found that such order as the main alloying element manganese products tensile stress More than 1000MPa, total elongation can be increased by 50%, both good formability, strength, ductility and strain hardening of weight loss, shock and to improve vehicle crash safety is very useful.
