The adiabatic compression of metals in the split-Hopkinson pressure bar is associated with a rise in temperature due to the dissipation of work energy. Previous experiments on high strain-rate deformed zirconium have measured nearly complete dissipation of plastic work as heat for specimens with a non-basal texture. In contrast, basal textured specimens exhibit incomplete dissipation and show evidence of localization by postmortem analysis. Active deformation mechanisms in basal textures include slip in basal oriented grains, and twinning in nonbasal oriented grains. The current study explores the effect of length scale on the development of local stress gradients by comparing strain fields gathered from digital image correlation to the undeformed grain structure and the initial crystallographic orientations as these mechanisms occur. It is seen that the crystallographic texture in basal samples encourages the development of local strain gradients, which at larger bulk strains will eventually lead to macroscale localization.
