Steels often have anisotropic mechanical properties due to texture or internal stress generated by deformation. Recently it has become desirable to control this anisotropy, to either eliminate it or exploit it in particular applications. The proposed experiment aims to measure the internal stress contribution to anisotropy by measuring internal strain evolution in dual phase steels during deformation along different strain paths. In a first experiment, we successfully obtained data for the reverse loading of a single-phase steel and now we would like to obtain data for a dual phase steel (ferritic-martensitic). This work is part of a larger research project at the University of Manchester and Nippon Steel and Sumitomo Metal Corporation. The aim of the project is to develop models for prediction of anisotropy, contributing to the development of new steels with controlled anisotropy.
