US09593392B2 Method for producing workpieces from lightweight steel having material properties that are adjustable across the wall thickness 有权
用于从轻质钢制造工件的方法，其具有可在整个壁厚度上调节的材料特性

Method for producing workpieces from lightweight steel having material properties that are adjustable across the wall thickness
Abstract:
A method for producing a workpiece having properties which are adjustable across a wall thickness or strip thickness of the workpiece, includes the steps of subjecting the workpiece to a decarburizing annealing treatment under an oxidizing atmosphere and to an accelerated cooling and/or a cold forming for generating a property gradient of the workpiece, wherein the workpiece is made of an austenitic lightweight steel which has an alloy composition which includes by weight percent 0.2% to 1% carbon, 0.05% to
Abstract(Chinese):

一种用于制造具有可在工件的壁厚或带材厚度上调节的特性的工件的方法包括以下步骤：对工件进行在氧化气氛下的脱碳退火处理和加速冷却和/或冷成型 产生工件的性能梯度，其中工件由奥氏体轻质钢制成，其具有包括重量百分比为0.2％至1％的碳，0.05％至15％的铝，0.05％至6.0％的硅， 9％至<30％的锰，以及选自铬，铜，硼，钛，锆，钒和铌中的至少一种元素，其中铬= 4.0％; 钛+锆= 0.7％; 铌+钒= 0.5％，硼= 1％，剩余的铁包括普通钢伴侣元素。
