Dislocation creep

Dislocation creep is a mechanism of plastic deformation that occurs in crystalline materials, particularly metals and geological materials, under conditions of high temperature and stress. It involves the movement of dislocations, which are line defects in the crystal structure. Key characteristics of dislocation creep include: 1. **Temperature Dependence**: Dislocation creep typically occurs at elevated temperatures (usually a significant fraction of the material's melting temperature) where atomic mobility is enhanced, allowing dislocations to move more freely.
