Initial Stages of Subgrain Formation as a Plastic Instability
Original language description
Localization of plastic strain in a form of shear bands or persistent slip bands, and disorietation of the crystal lattice appearing as disoriented dislocation cells or subgrains are typical features of advanced stages of plastic deformation and creep.Itis suggested that both localization and lattice disorientation can be interpreted as instabilities of homogeneous plastic deformation of a continuum mechanics origin. Localization occurs when hardening coefficient approaches zero. Lattice disorientat ion is a consequence of sufficiently strong plastic anisotropy provided either by differences in active and latent hardening or by glide and climb properties of dislocations. The outlined constitutive framework follows the theory of Biot, and Hill and Hutchinson. The formation of subgrains in creep is treated in detail as an example
