Dynamic compressive stress-strain curves of aluminum alloy 6061-T6 with rapid heating

Description

This dataset contains raw mechanical data (strain, stress and strain rate curvesand initial temperatures) for compression experiments performed on aluminum alloy 6061-T6using the NIST pulse-heated Kolsky Bar at strain rates between 2400 1/s and 2700 1/s and initialtemperatures from 23 °C to 527 °C and heating times ranging between 0.2 s and 3.5 s. At this time,the thermal history of the specimen during heating is not included in the dataset but this informationmay be included in a future update. The pulse-heated Kolsky bar method is described in reference [1].Additional information regarding the temperature measurement methods specific to aluminum are found inreference [2] as well as a supplementary included in this data publication [3]. This datasetincludes measurements of right-circular cylindrical samples measuring 6 mm diameter by 3 mm thick,fabricated by conventional machining. The effect of the surface condition on the thermographic temperature measurements and the temperature uncertainty calculations are described in reference [3], which is included in this dataset as metadata.[1] Mates, S.P., et al., A Pulse-Heated Kolsky Bar Technique for Measuring the Flow Stress of Metals at High Loading and Heating Rates.
