The sample was loaded to just beyond the yield point, and then held at constant strain for 5 minutes over which time the stress relaxed. The sample was then reloaded elastically and a further period of stress relaxation at fixed total strain undertaken. in total five periods of stress relaxation were imposed. Throughout the mechanical testing cycle powder diffraction patterns were recorded in the transmission geometry,at 1 second intervals using a 2d Pixium detector held 1097 mm from the sample. The beam energy was determined to be 79.79 keV. Diffraction Patterns are contained as 16 bit TIF files bundled into the Patterns_72995.zip file. Macroscopic mechanical test data are in the excel file MechTest_2995.xlsx. Small EBSD map in #.ctf format converted from Bruker #bcf file inCPg4.ctf file. Matlab + MTEX script to load and make simple plots from EBSD data file inCPg4Ti_EBSDmap.m file.
