Abstract

This article presents a review of current results of theoretical and experimental studies of the specific features of the structure that is formed in high-strength low-alloy steel in the process of hot rolling and which determines the properties of the steel. The current concepts of the physical processes that are developed at different stages of a thermomechanical treatment depending on the temperature–strain-rate regimes and chemical composition of the steel are considered. Particular attention is paid to the problems of the formation of the structural state that continue to be debated. The simulation methods of different scale level used to solve the problems of controlling structure formation at all stages of thermomechanical processing process are discussed.
