Abstract Scope A challenge for understanding and predicting hexagonal titanium alloy deformation is the availability of different families of slip systems to accommodate plastic deformation, each with their own strengths, hardening behaviors, and rate sensitivities. Traditional single crystal mechanical testing has long struggled with deconvolving the activity of various slip systems leading to deficiencies in micromechanical modeling efforts. The advent of various synchrotron X-ray diffraction techniques, including high-energy diffraction microscopy (HEDM) which can probe large numbers of crystals and loading conditions in situ, is providing a new means to address this challenge. Here a series of efforts to understand the microscale crystallographic slip behavior of titanium alloys using synchrotron X-ray measurements will be presented.
