Figure 7. mGSF/CRSS evaluates the activity of the twin and slip systems during (A) FET and (B) RFET, the mGSF is calculated as the average of the maximum mGSF of all grains in (0001)-IPF. CRSS: Critical resolved shear stress; FET: free end torsion; ED: extrusion direction; RFET: reverse FET; mGSF: global Schmid factor.
