Stress-strain data for aluminum 6061-T651 from 9 lots at 6 temperatures under uniaxial and plane strain tension

Abstract

Stress-strain curves in steady-state tension of aluminum 6061-T651 sourced from 9 lots of material from several manufacturers at 6 temperatures (20,100,150,200,250,300 °C) are presented. A total of 100 stress-strain curves for uniaxial tension specimens and 54 stress-strain curves for plane strain tension specimens are shared. Strains are estimated through digital image correlation using a 50.8 mm (2 inch) gauge length for the uniaxial tension specimens and a 6.35 mm (0.25 inch) gauge length for the plane strain specimens. The strains are an average of several measurements (at approximately 350-μm intervals) across the width of the gauge section.
