Abstract
Isothermal Bainite Transformation (IBT) generates heterogeneous grain structures, leading to increased strain-hardening ability and inhibiting yield plateau and stress serrations. IA-steel and IBT-steel have ultimate tensile strengths of 1306 MPa, 1354 MPa, and elongations of 20.0%, 19.2%, respectively. IBT effectively suppresses plastic instability while maintaining mechanical properties.
