Abstract

In this study, we investigate the effects of shear and compressive deformation on microstructural evolution during hot working of low carbon micro-alloyed steel containing 0.03 mass% Nb. By systematically introducing shear and compressive strains under controlled conditions, we clarified the role of shear strain in phase transformation and grain refinement. Results show that when the equivalent strain exceeds 2 with shear strain (γ ≈ 2.2) at 800 °C, effective nucleation sites are generated, promoting the formation of ultrafine ferrite grains (
