Abstract
ABSTRACT The present work quantifies the contribution of constituting phases to the strain hardening in a medium-Mn steel during Lüders deformation. The strain hardening of the ferrite matrix (∼ 46.1 MPa) is much lower than that of the austenite phase (∼ 116 MPa). The large difference of strain hardening behaviour between ferrite and austenite phases is ascribed to a martensitic transformation. Thus, the transformation-induced plasticity effect in retained austenite is the main contributor to the strain hardening during Lüders deformation of the present medium-Mn steel.
期刊介绍：
Philosophical Magazine Letters is the rapid communications part of the highly respected Philosophical Magazine, which was first published in 1798. Its Editors consider for publication short and timely contributions in the field of condensed matter describing original results, theories and concepts relating to the structure and properties of crystalline materials, ceramics, polymers, glasses, amorphous films, composites and soft matter. Articles emphasizing experimental, theoretical and modelling studies on solids, especially those that interpret behaviour on a microscopic, atomic or electronic scale, are particularly appropriate.
Manuscripts are considered on the strict condition that they have been submitted only to Philosophical Magazine Letters , that they have not been published already, and that they are not under consideration for publication elsewhere.
