Due to their unique mechanical properties, hexagonal close-packed (HCP) polycrystals are extensively used in various industries. The life span of HCP components are generally affected by the localized stress or strain fields that develop as a result of an applied mechanical load. In this presentation, examples of various sources of stress localization in HCP polycrystals will be discussed. High resolution electron backscatter diffraction technique is used for measuring such localized deformation fields, while crystal plasticity finite element method is used for further analysis of the measured microstructures. Such coupling is crucial for understanding the mechanism of stress localization and for the development of advanced materials constitutive models.
