C3 Atomistic simulations of elementary dislocation processes in coherent and semi-coherent γ/γ’-microstructures: influence of temperature and alloying elements
The main objective of project C3 is to provide a better understanding of the interaction mechanisms between dislocations and γ/γ’-interfaces, and of the processes during dislocation climb. This requires modeling the complex interplay between dislocations, stress fields, diffusion and the local chemical composition at the interfaces. For this purpose, classic atomistic simulation approaches with newly developed potentials will be used alongside cutting-edge methods like diffusive molecular dynamics. The results of C3 will be analyzed in close collaboration with the A-projects and form key elements of the multiscale modeling framework of SFB/TR 103.
