The plausibility of <c + a> dislocation slip on {-12-11} planes in Mg

Dear Colleagues,

Please see the link for a recent article published in Scripta Materialia. In this article, active cross-slip behavior of screw <c + a> dislocations in Mg is observed, and the plausibility of <c + a> dislocation slip on new planes {-12-11} that have hitherto not been considered possible, is shown for the first time.

Surface roughness evolution during early stages of mechanical cyclic loading

The effect of crystal size and initial dislocation density on surface roughness evolution in FCC single crystals during the early number of cycles of mechanical cyclic loading is investigated using three dimensional discrete dislocation dynamics simulations. Crystals having size less than 2 μm show early development of surface slip localization, while larger ones show a more uniform distribution of surface steps. The surface roughness is found to increase with increasing number of loading cycles with larger crystals showing a high roughening rate compared to smaller crystals.

Microstructurally based cross-slip mechanisms and their effects on dislocation microstructure evolution in fcc crystals

Three newly identified cross-slip mechanisms from atomistic simulations of fcc crystals, namely surface, bulk and intersection cross-slip types, were hierarchically informed into discrete dislocation dynamics simulations. The influence of each cross-slip type on the evolution of the dislocation microstructure in face-centered cubic microcrystals having different crystal sizes and initial dislocation densities was investigated.
