In the present investigation, a coupled crystal plasticity finite-element (CPFE) and cellular automaton (CA) model was developed to predict the microstructure of recrystallization in single-crystal (SX) Ni-based superalloy. The quasi-static compressive tests of [001] orientated SX DD6 superalloy were conducted on Gleeble3500 tester to calibrate the CPFE model based on crystal slip kinematics. The...
Many kinetics theories assume that nucleation of a new phase takes place on sites that are randomly located within the parent matrix. In practice, however, nuclei form at non-random sites. These sites could be situated, for example, on grain boundaries or within a heavily deformed grain or deformation band. Applying formal kinetics theories to reactions in which sites are non-randomly located may...
