Abstract
The Si addition facilitates the partitioning of carbon to κ-carbide during aging in a Fe–30Mn–9Al–0.9C–0.5Mo lightweight steel, i.e. from (Fe,Mn)3AlC0.38 to (Fe,Mn)3AlC0.51. Reduced plasticity was found in 1% Si-added specimen where one directional shearing of κ-carbide was prominent. Novel insights into dislocation-κ-carbide interactions are discussed in terms of atomistic shear. © 2016 Elsevier B.V.
