KEY FEATURES:A unified, fundamental and quantitative resource. The result of 5 years of investigation from researchers around the worldNew data from a range of new techniques, including synchrotron radiation X-ray topography provide safer and surer methods of identifying deformation mechanisms Informing the future direction of research in intermediate and high temperature processes by providing original treatment of dislocation climb
