Abstract

Abstract Segregation is an unavoidable phenomenon in continuous or ingot casting of steel for thermodynamic reasons. If costly processes that explicitly reduce segregation are not carried out, the segregations remain until the final product. Therefore, an understanding of the development and effects of segregation along the entire process chain is necessary. The focus in this publication is on the treatment of segregations in low alloy steels. First, the characterisation of segregation is presented. An overview of the formation and development of segregations during primary shaping and forming processes is given. The focus is on segregation-related effects during heat treatment with regard to inhomogeneous microstructure and negative heat treatment results such as distortion or hardening cracks. In a short outlook, the influence of segregation on the component behaviour is described. ◼
钢在热处理过程中的偏析——沿工艺链的考虑
摘要由于热力学原因,偏析是连铸或铸锭过程中不可避免的现象。如果没有采用成本高昂的明确减少分离的工艺,那么分离就会一直存在,直到最终产品出现。因此,了解沿整个过程链的分离的发展和影响是必要的。本出版物的重点是低合金钢中偏析的处理。首先,介绍了偏析的特征。概述了初生成形和成形过程中偏析的形成和发展。重点是在热处理过程中对不均匀组织和负面热处理结果(如变形或硬化裂纹)的偏析相关影响。在一个简短的展望中,描述了隔离对组件行为的影响。◼
