Steels often have anisotropic mechanical properties due to texture or internal stress generated by cold 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 steels during deformation along different strain paths. It will make up part of a larger research project at the University of Manchester and the PhD work of Kensuke Nagai, who is on study leave from Nippon Steel. The aim of the project is to develop models for prediction of anisotropy, contributing to the development of new steels with controlled anisotropy.
