Dislocation Structures in Metallic Single Crystals Grown from the Melt

  • I. K. Zasimchuk
Part of the Growth of Crystals book series (GROC, volume 17)


Possible sources of dislocations and other imperfections in single crystals grown from the melt were discussed about 30 years ago. These sources are: 1) stacking faults and stresses at the interface; 2) stresses caused by inhomogeneous temperature or impurity distribution, as well as inclusions of a second phase or the vessel; 3) thermally nonequilibrated vacancies (or intrinsic interstitial atoms); and 4) small-angle boundaries and dislocations from the seed.
