Abstract

The paper presents a model for predicting the structural characteristics and phase composition of low-alloy steels upon hot rolling in the multi-pass deformation mode. The model considers recovery, dynamic, primary, dynamic and static recrystallization of grains, and the normal grain growth, as well as nucleation (including accelerated nucleation during deformation), growth or dissolution, and coarsening of carbonitride particles. The comparison between the calculated results and the experimental data available in the publications shows a satisfactory agreement.

模拟低合金钢多道热变形时相组成和奥氏体晶粒尺寸的演变
摘要 本文提出了一种用于预测低合金钢在多道次变形模式下进行热轧时的结构特征和相组成的模型。该模型考虑了晶粒的恢复、动态、初生、动态和静态再结晶、正常晶粒生长以及碳氮化物颗粒的成核(包括变形过程中的加速成核)、生长或溶解和粗化。将计算结果与出版物中的实验数据进行比较,结果显示两者的一致性令人满意。

期刊介绍: The Physics of Metals and Metallography (Fizika metallov i metallovedenie) was founded in 1955 by the USSR Academy of Sciences. Its scientific profile involves the theory of metals and metal alloys, their electrical and magnetic properties, as well as their structure, phase transformations, and principal mechanical properties. The journal also publishes scientific reviews and papers written by experts involved in fundamental, application, and technological studies. The annual volume of publications amounts to some 250 papers submitted from 100 leading national scientific institutions.
