Dynamic grain boundary region deformation of pure magnesium was investigated and verified by utilizing in-situ full field strain measurements obtained from Digital Image Correlation (DIC) techniques. This method was confirmed to effectively characterize the microstructural response of an area of interest in the vicinity of multiple grain boundaries and triple junctions. The highly heterogeneous evolution of the material strain patterns was quantified, and the highest concentrations of the localized response were seen to occur primarily at the interfaces between grains, while the amount of in-grain deformation, specifically in the larger grains was minimal by comparison. Locations of suspected active slip and twinning regions were identified and conclusions about other possible modes of deformation are discussed.
