Modeling dislocation cutting the precipitate in nickel-based single crystal superalloy via the discrete dislocation dynamics with SISF dissociation scheme.

Highlights: [•] The SISF dissociation scheme is introduced into the present 3D-DDD framework. [•] The two typical stages of the APB-SISF transition are successfully captured. [•] The results considering SISF and APB dissociations are closer to experiments. [Copyright &y& Elsevier]
