Abstract: Abstract Screw dislocation cross-slip is important in dynamic recovery of deformed metals. A mobile screw dislocation segment can cross slip to annihilate an immobile screw dislocation segment with opposite Burgers vector, leaving excess dislocations of… read more here.

Abstract: Abstract The cross-slip rate of screw segments in dislocation dynamics simulations was calculated using the model of Esteban-Manzanares et al. (2020), which is based on a combination of the harmonic transition state theory and the Meyer-Neldel… read more here.

DOI: 10.12693/aphyspola.134.667
Abstract: In this paper we develop a model for double cross-slip in fcc crystals. The double cross-slip mechanism is demonstrated by a simulation of an overcoming of a particle exerting spherically symmetric repulsive stress field. The… read more here.
