Abstract
The effect of deformation on grain growth during straining-dynamic grain gr owth-of polycrystals nominally at the Zener limit has been considered. Both homogeneous deformation, and deformation which is inhomogeneous as a resul t of intergranular plastic anisotropy, give perturbations of geometry which lead to grain growth with strain. There may be further contributions which reduce Zener drag during straining, and these would have a significant eff ect. These cases have been modelled as two-dimensional approximations, and this modelling shows that the geometric effects of deformation on grain gro wth in particle-containing systems could be a major contributor to the dyna mic grain growth observed in practice.
