Additional information

This paper challenges the basis of a long held relationship in materials science concerning the strengthening of metals with reducing crystal size. This ‘Hall-Petch’ relationship has been taught in all first year materials science and metallurgy degrees since the 1950s. We show the relationship is wrong and that a much simpler relationship explains both this and other size dependent phenomena. This work requires that the text books on metal strengthening should be re-written. The paper has attracted invited keynote talks at four international conferences 'Plasticity 2014', TMS Madrid 2013, ECI Nanomechanics 2013 and MS&T Montreal 2013.
