Calibration (Prismatic slip) of the new dislocation density based CPFE model for single crystal alpha-Ti (Titanmod). Formulated edge and screw dislocations mobilities in presence of kink pairs. Updated comments. The model shows the plateau in stress evolution in prismatic orientation which is observed in experiments.
