“…Figure 9 shows the relationship between the number of JM pass and the absorbed energy, i.e., integrated area under the tensile stress-strain (uniform or fracture strain) curve. Absorbed energy estimated by integrating the stress-strain curve until fracture can be regarded as toughness 17) of the material under investigation. It can be observed that the absorbed energy of the compacts under quasi-static tensile loading increased with increasing number of jet milling passes up to 3 passes.…”

Through many years, conventional material developments have emphasized on microstructural refinement and homogeneity. However, "Nano-and Homogeneous" microstructures do not, usually, satisfy the need to be both strong and ductile, due to the plastic instability in the early stage of the deformation. As opposed to such a "nano-and homo-"microstructure design, we have proposed "Harmonic Structure" design. The harmonic structure has a heterogeneous microstructure consisting of bimodal grain size together with a controlled and specific topological distribution of fine and coarse grains. In other words, the harmonic structure is heterogeneous on micro-but homogeneous on macro-scales. In the present work, the harmonic structure design has been applied to pure-Ti via a novel powder metallurgy route consisting of controlled severe plastic deformation of the fine-sized powder particles via jet milling and subsequent consolidation by SPS. At a macro-scale, the harmonic structure materials exhibited significantly better combination of strength and ductility, under quasi-static tensile loadings, as compared to their homogeneous microstructure counterparts.
