extended dislocation

[ik′stend·əd ‚dis‚lō′kā·shən]

(crystallography)

A dislocation in a close-packed structure consisting of a strip of stacking fault edged by two lines across which slip through a fraction of a lattice constant, into one of the alternative stacking positions, has occurred.

The first one, based on Fourier series and the concept of extended dislocation core, is developed in the present work from an appropriate combination of partial results obtained in [20, 22].

Threading Dislocations Piercing the Free Surface of an Anisotropic Hexagonal Crystal: Review of Theoretical Approaches

The attached partial dislocation and stacking fault at both ends are collectively described as extended dislocation.

The high resolution electron photomicrograph of the sample was investigated and extended dislocation was found in a phase.

In addition, because the slip is easier to be produced in [beta] phase, the extended dislocation is difficult to be seen, which reflects that the stacking fault energy is higher in [beta] phase than in a phase.

At mentioned strain structural changes were registered, connected with dynamic return: partial disintegration of cellular structure and formation of dense extended dislocation accumulations (fragments) with angular disturbance 3-5[degrees].
