安全、節(jié)約燃料、抗表面凹陷和追求舒適是汽車(chē)行業(yè)的一大進(jìn)步。其中節(jié)約能源是汽車(chē)行業(yè)鋼材用戶們最重要的目標(biāo)之一。但是，通常對(duì)于一個(gè)給定的冶金工藝來(lái)說(shuō)，抗拉強(qiáng)度的增加會(huì)導(dǎo)致延性的損失。Arcelor開(kāi)發(fā)的系列高錳合金鋼（被稱為FeMnTWIP1000鋼）正試圖達(dá)到汽車(chē)行業(yè)所要求的最佳力學(xué)性能和使用性能。

D.Cornette等人通過(guò)對(duì)FeMnTWIP1000鋼顯微組織、變形方式、材料性能、成形性能、撞擊特性、疲勞性能、可焊性的大量研究發(fā)現(xiàn)，這類(lèi)以錳為主要合金化元素的產(chǎn)品拉伸應(yīng)力超過(guò)1000MPa，總延伸率可提高50%，兼具良好的成形性、強(qiáng)度、延性和應(yīng)變硬化特性，對(duì)減重、抗沖擊和提高汽車(chē)撞擊安全性非常有用。

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.
