Influence of Deformation and Heat Treatment on the Microstructure and Properties of High-Strength Low-Alloy Steel with Boron

Steel in Translation Aims and scope

Abstract

The microstructure, fine structure, and mechanical properties of high-strength low-alloy steel with boron are studied after two different rolling technologies: (1) high-temperature hot rolling; (2) two-stage controlled rolling with accelerated cooling and subsequent quenching with tempering. The tempering temperature corresponding to irreversible tempering brittleness of the first kind is established. The reasons for embrittlement at that temperature are analyzed.
