Abstract

The influence of the temperature–deformation parameters on the structure formation and the development of dynamic recrystallization (DR) in austenitic corrosion-resistant steel during high-temperature thermomechanical treatment is studied. The stress–strain state during the production of an angle is analyzed. Technological DR diagrams are constructed, and the recrystallized-structure distribution over the cross section of the angle product is estimated. A finite element model has been developed to estimate the DR of shaped sections made of 08Kh18N10T steel.

奥氏体耐蚀钢高温热机械处理形成复杂断面过程中动态再结晶的模拟

摘要

研究了高温热机械处理过程中温度-变形参数对奥氏体耐腐蚀钢组织形成和动态再结晶（DR）发展的影响。分析了角钢生产过程中的应力-应变状态。构建了技术 DR 图，并估计了角积横截面上的再结晶结构分布。已经开发了一个有限元模型来估计由 08Kh18N10T 钢制成的异形截面的 DR。
