Some theoretical problems of thermomechanical treatment for the nonmagnetic high strength steel 50Mn18Cr4 closely related to energy resources science were studied. The steel was frequently scrapped because of its coarse or inequable grain size in the final workhardening process.In an attempt to overcome the difficulties occuring in producing generator retaining rings, this paper dealt mainly with the regular pattern of the micro structural change and high temperature recrystallization in steel tested instead of concrete technological parameters. A new tripartite envisage of producing retaining rings was proposed. That is:( 1 ) to make the electroslag casting ring;( 2 ) high temperature controlled hot deformation followed by controlled cooling (i.e. high temperature thermomechanical treatment);( 3 ) cold deformation strengthening.The present investigation provides a theoretical foundation for the second step only. The connexion with the first step is considered also.

本文对与能源科学密切相关的无磁奥氏体高强度结构钢50Mn18Cr4高温形变热处理的理论问题进行了研究。这种钢常常因其粗大或不均匀的晶粒尺寸而在最终的形变强化工序中报废。作者试图解决发电机护环生产实践中大批产品的这一类不合格问题。研究内容不是具体的工艺参数,而是研究该钢的组织变化和高温再结晶的规律。由此提出新的护环生产工艺设想。它由如下三步组成:(1)电渣熔铸环坯→(2)高温控制热变形和控制冷却(即高温形变热处)→(3)冷变形强化。本文内容仅为第二步的理论基础,但考虑了与第一步之间的衔接。

The microstructure of the steel wire in quenching state is mainly lath martensite. The steel wire treated under better processing condition can satisfy the performance requirements for springs or steel wire ropes.
