High-temperature plasticity of microalloyed steel

Steel in Translation Aims and scope

Abstract

The influence of continuous casting of steel on the high-temperature plasticity of microalloyed steel is investigated. The Gleeble-3800 system is used for the physical modeling of the steel’s hot plasticity. The temperature ranges of plasticity are determined in different conditions of slab cooling in the continuouscasting machine. In all the simulations, a trough is seen on the temperature dependence of the steel’s plasticity. With enlargement of the grain boundaries (decrease in grain size), the high-temperature plasticity increases.
