Abstract Scope |
During creep multiple processes occur simultaneously, straining just beyond the elastic limit while diffusion, especially along grain boundaries, can play a significant role. In self-healing creep steels the accumulation of vacancies, which ultimately leads to nanovoid formation, can be countered by grain boundary segregation and localized precipitation. In the presentation the role of highly localized non-average (deviatoric) stresses at grain boundaries on diffusional fluxes and precipitation will be discussed. |
