Stress-strain and microscopy data for fire-damaged aluminum alloy 6061 subjected to multiaxial loading

Abstract

Stress/strain data from mechanical testing of samples obtained from “as received” and fire damaged (400 °C and 500 °C) aluminum alloy 6061 plates is reported. Mechanical load information was obtained from load cells in the mechanical testing system while strain data was obtained from a digital imaging correlation system. For each plate condition (as received, 400 °C, 500 °C), four samples were machined along and across the rolling direction and subjected to four mechanical tests (tension, torsion, two combined tension/torsion tests) for a total of 24 unique combinations of condition, machining direction and loading path. Data from mechanical testing and digital imaging correlation systems was interpolated to generate stress/strain curves. Included data repository allows regeneration of stress/strain curves presented herein. Microscopy samples were obtained both from undeformed plates and deformed samples. Subsequent to polishing, EBSD was carried out and obtained microstructure and pole figures are reported.
