    Dislocation theory and transient creep
    (Physical Society, 1948) Mott, N.F.; Nabarro, F.R.N.
    The purpose of this paper is to put forward certain advances in the theory of dislocations, and in particular to discuss their application to the theory of transient creep, in the sense in which the term is used by Andrade (1911, 1914, 1932) and by Orowan (1947).

    An attempt to estimate the degree of precipitation hardening, with a simple model
    (Physical Society, 1940) Mott, N.F.; Nabarro, F.R.N.
    The process of diffusion being assumed to result simply in an interchange of atoms, an estimate is made of the internal strains produced by precipitation. According to the dislocation theory these strains are responsible for the hardness of the material, and so the degree of hardening can be predicted.
