Sample and materials * Material: 6016 T4 aluminum alloy * Average grain size: 40 µm * Shape: Wide dogbone to fulfil plane strain conditions during tensile deformation Experiment and characterisation * LabDCT grain map of interior volume of undeformed sample * X-ray imaging equipment: Zeiss Xradia 520 Versa X-ray microscope with LabDCT Pro module * Absorption contrast scan: 60kV-4W, 4X detector, 1601 projections, 4.45 µm voxel size * Diffraction contrast scan: 110kV-9W, flat panel detector, helical phyllotaxis HART scanning scheme, 1800 projections Data * Map dimensions: - x = 0.44 mm (sample thickness) - y = 0.24 mm (direction of near-zero strain in the plane strain condition, ~6 grain diameters width) - z = 1.00 mm (tensile direction) * Voxel size: 4 µm * Number of grains: 1666, all of which are at least 27 voxels, and no voids * Context: This is a cropped volume at the center of the sample, not the full volume analysed in the associated publication * Format: .h5
