Abstract

A variety of surface observational techniques including full-field strain mapping based on digital image correlation analysis, electron back-scatter diffraction and in situ field emission scanning electron microscopy have been used to follow the patterns of inhomogeneous flow which occur during tensile testing of AA5754. The observations permit the relationships between slip lines, dynamic strain aging, shear localization, diffuse and localized necking to be delineated. In addition, fracture observation and metallographic assessment of damage processes have been conducted to enable an understanding of the relationship between inhomogeneous deformation and ductility to be developed.
