Solute-dislocation
interactions in metal alloys
Many important properties of structural
materials are influenced by interactions between solute atoms and
dislocations. Although the solute-dislocation interaction energy may be
found directly in principle, the computational resources for such a
calculation are not tractable.
Our research focuses on the developing a continuum theory that allows
the undersanding of the nature of this interaction using first
principles calculations of only small clusters of atoms. The results
enable the studies of elastic and magnetic contributions to the
solute-dislocation interactions.
