Figure 5

(a,b) Digital images of strain rate and (c,d) strain rate distribution curves of the TWIP and T2L sheets at tensile strains of 33.5%, 35.9%, and 37.8%. In the TWIP sheet, the localization of strain rate occurs in a form of band at the lower region of the gage section at the strain of 33.5%. This localized band moves upward as the strain increases to 35.9% and 37.8%. In the T2L sheet, the localized band is not found throughout the gage section, and the strain rate is almost same to the overall strain rate (0.1%/s) of the tensile test.
