Abstract

A phase-field model was used for investigating the dynamic interactions between moving dislocations and diffusive solutes. In the solute solution the chemical interaction, and the elastic interactions among the dislocations and solutes were considered. In between a single dislocation and its solute atmosphere, some features of dynamic interactions were revealed by the simulations performed. Three characteristic values were displayed by the average velocity of the dislocation that depended on the ratio of solute mobility and dislocation mobility, the overall composition, and the applied stresses.
