Insights on activation enthalpy for non-Schmid slip in body-centered cubic metals
Scripta materialia, v 99, pp 89-92

Abstract
We use insights gained from atomistic simulation to develop an activation enthalpy model for dislocation slip in body-centered cubic iron. Using a classical potential that predicts dislocation core stabilities consistent with ab initio predictions, we quantify the non-Schmid stress-dependent effects of slip. The kink-pair activation enthalpy is evaluated and a model is identified as a function of the general stress state. Our model enlarges the applicability of the classic Kocks activation enthalpy model to materials with non-Schmid behavior. (C) 2014 Acta Materialia Inc. Published by Elsevier Ltd.
