引言低碳冷轧钢板的主要使用性能是深冲性能,而决定深冲性能的主要冶金因素是再结晶织构,这已为近十余年来大量的生产实践及科研工作所证实。深冲性能所要求的有利织构应保证薄板具有垂直塑性各向异性,亦即要求薄板在厚度方向的强度大于平均强度,这样就可以保证薄板在冲压成形时主要由板面内的塑性流动完成而不易减薄,因而就可减少冲压破损率。从晶体学考虑,为获得这样的塑性各向异性需要再结晶后各晶粒的<111>晶轴垂直
Introduction The main serviceability of low-carbon cold-rolled steel sheet is deep drawability. The main metallurgical factor that determines deep drawability is recrystallization texture, which has been confirmed by a large number of production practices and scientific research over the past decade. The favorable texture required for deep drawability should ensure that the sheet has perpendicular plastic anisotropy, ie, the strength of the sheet in the direction of the thickness is greater than the average strength, so that the sheet can be ensured mainly by the plastic flow in the sheet during press forming And not easy to thin, so you can reduce the rate of stamping damage. From the crystallographic point of view, in order to obtain such plastic anisotropy, it is necessary to crystallize the <111> crystal axis of each crystal grain after recrystallization
