Atomistic study of diffusion-mediated plasticity and creep using phase field crystal methods
Abstract
The nonequilibrium dynamics of diffusion-mediated plasticity and creep in materials subjected to constant load at high homologous temperatures is studied atomistically using phase field crystal (PFC) methods. Creep stress and grain size exponents obtained for nanopolycrystalline systems, m≃1.02 and p≃1.98, respectively, closely match those expected for idealized diffusional Nabarro-Herring creep. These exponents are observed in the presence of …
