Abstract
Recently, a new concept of diffusion and inelastic strain in multi-component systems with non-ideal sources and sinks for vacancies has been presented, accounting for both chemical and mechanical driving forces. Based on this concept, chemically driven diffusion and inelastic deformation in an Fe-Mn-C-vacancy system, consisting of a bamboo-structured load-free wire, are investigated in the present paper. Simulations demonstrate that the evolution of the inelastic deformation depends on the activity of sources and sinks for vacancies represented by grain boundaries and jogs at dislocations. The evolution of the chemical composition is, however, practically not influenced by the activity of sources and sinks for vacancies in the studied system.
