Harmonic structure (HS) design is one of the heterogeneous microstructure designs, and it is heterogeneous on micro-but homogeneous on macro-scales. In the present work, the HS design has been applied to various kinds of metals and alloys via a powder metallurgy route consisting of controlled severe plastic deformation, and subsequent sintering. The HS materials exhibited superior combination of strength and ductility, as well as tensile toughness, as compared to their homogeneous microstructure counterparts. Noteworthy is that the HS materials indicate “micro-scale stress concentration” and “macro-scale strain dispersion” which lead to a large work hardening and a large uniform elongation without deformation localization.
