Experimental study of an aerospace titanium alloy under various thermal and tensile loading rate conditions

Microstructure characterization and tensile testing was performed on flat samples machined from a 4.77-mm-thick sheet of Ti-6Al-2Sn-4Zr-2Mo-0.1Si at a range of temperatures (23 °C up to 650 °C) and two strain rates (8.33 × 10−5/s and 10−2/s). A minimum of three repeats were conducted at each test condition. Each test recorded load, displacement, strain, time, and temperature for the duration of the test, and the complete raw data files are provided along with area measurements. The dataset demonstrates the changing strain rate and temperature sensitivity to the yield stress, work-hardening slope, and the ultimate stress. The completeness of this dataset and its possible applications are discussed. The complete data files that were collected along with specimen measurements and microstructural texture files are available at the National Institute of Standards and Technology (NIST) repository .
