Abstract Scope Near-alpha titanium alloys often exhibit regions containing alpha phase grains of similar c-axis orientation, called microtexture regions (MTRs). These MTRs are considered an important factor in dwell fatigue life behavior, with certain characteristic features of MTRs, such as size, c-axis misalignment, and density, driving a fatigue life debit. MTRs are can be visually identified by human inspection of orientation maps obtained from electron backscatter diffraction (EBSD); automatic techniques for their identification are desirable, but suffer from sensitivity to input parameters and resolution. We present a canonical EBSD data set of Ti-6Al-4V to serve as a representative standard for assessing techniques for MTR segmentation and quantification. This data set includes systematic variations in resolution and simulated transformed beta area fraction. We showcase a variety of segmentation procedures for identifying the MTRs, and quantify the sensitivity of computed MTR metrics to the data set characteristics and analysis parameters.
