Abstract

Dislocation–dislocation interactions are investigated in α-iron using dislocation dynamics (DD) simulations. Special attention is paid to the simulation conditions and parameters to reveal the domain of validity of the calculations. Interaction coefficients between the {11¯0}〈111〉 slip systems are computed and analyzed in connection with the dislocation microstructures developed during simulations. The so obtained crystalline law is used to predict the flow stress in a massive DD simulation of a tensile test in duplex slip condition.
