abstract = "We have succeeded in designing a {"}Harmonic Structure Material{"} through use of one of the non-equilihrium powder metallurgy processes called the severe plastic deformation powder metallurgy process. The harmonic material has a network structure of continuously connected {"}shell{"} with finer grains and a dispersive structure of coarse-grained {"}core{"}. The harmonic structured materials simultaneously demonstrate both high strength and good ductility. In the present study, the fatigue property of commercially pure titanium with harmonic microstructure was investigated and it exhibited enhanced fatigue limit compared with that of homogeneous coarse-grained counterpart. The initiation and propagation behaviors of fatigue cracks were examined based on observing the surface cracks and fracture surface. The role of the microstructural inhomogeneity was discussed.",
