Dislocation structure dynamics in a nonstationary temperature field /Review/
Abstract
Dislocation dynamics in a nonstationary temperature field are reviewed. Attention is focused on semiconducting crystals with the diamond type lattice. The dislocation sources are considered responsible for a higher dislocation density in surface layers of the crystal in a periodically variable temperature field. The interaction kinetics of single dislocations with impurity atoms and the stability of dislocation structures formed in response to high-temperature treatment (annealing, thermocycling, high-temperature creep) are also discussed. Some regularities of dislocation dynamics common to a wide class of crystalline substances including metals are discussed.
