Bulk ultra-fine grained (UFG) and nanostructured (NS) materials have attracted immense interest in recent years due to
the paramount goal of achieving simultaneous increase in strength and ductility. A unique method for obtaining these
materials is the utilization of severe plastic deformation for structural refinement. Despite their technological importance in
industries ranging from automotive and aerospace to energy and biomedical; efforts on difficult-to-work hexagonal close
packed (hcp) materials have been comparably limited in quantity and scope. Robust utilization of UFG-NS materials in
engineering applications will not be possible without exploring the mechanical behavior within given operation envelopes,
typically not limited to ambient or monotonic conditions. This project aims to investigate the monotonic-cyclic response of
severely deformed hcp materials by exhibiting the interplay of unique deformation mechanisms at the micro-nano scale, and
strengthen the understanding of their effects on the observed mechanical behavior. With the aid of novel characterization
techniques, trends in the processing-structure-property relations among the model materials will be demonstrated. These
will be incorporated in physically sound constitutive models for improving the predictive capabilities. Ultimately, these
efforts will fill in the crucial missing gap between engineered microstructures and envisaged applications for European
competitiveness and welfare.
