A full field strain mapping technique based on digital image correlation analysis
has been used to observe the surface strain fields during tensile and low cycle
fatigue deformation of magnesium alloys Elektron WE43 and Elektron 21.
Heterogeneous strain fields are obtained from localized deformation in the
microstructure. The objective of this work is to correlate the locations of fatigue
crack initiation and fatigue crack growth with intergranular strains and the
distribution of microstructural features such as brittle intermetallic phases.
