The methods for the calculation of the elastic interaction of point defects with a dislocation loops in hexagonal crystals
Green's function method is used for hexagonal crystals according to Lifshitz-Rosenzweig and Kröner. Analytical expressions have been derived for the energy of elastic interaction of radiation point defects with dislocation edge loops of two types: c-loop (in the basal plane; the Burger’s vector...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Green's function method is used for hexagonal crystals according to Lifshitz-Rosenzweig and Kröner. Analytical expressions have been derived for the energy of elastic interaction of radiation point defects with dislocation edge loops of two types: c-loop (in the basal plane; the Burger’s vector bᴰ=½[0001]) and α-loop (in the plane {112¯0}, the Burger’s vector bᴰ=⅓[112¯0]). In the case of the basal loop an analogous expression is obtained by the independent solution of the equilibrium equations by the Eliot’s method. Numerical comparison of the expressions for zirconium showed complete identity of these approaches. |
