Elastic interaction of point defects with dislocations

Elastic interaction between dislocation and point defects with spherical symmetry is investigated theoretically by means of the sphere-in-hole model. The interaction energy due to the different elastic moduli of the point defect and matrix is computed and then added to the interaction energy due to the size effect. The force on and the probable position of the point defect is determined. The numerical results for some selected solute atoms are computed by means of available experimental data.The results are compared with other recent papers and some experimental applications are briefly discussed.The author is much indebted to F. Kroupa, CSc., for fruitful discussions and valuable comments.
