Abstract Harmonic structure consists of a powder particles surface with fine grains and particles core with coarse grains. The structure consists of a network-like fine grain region filled with islands of coarse grain region. The structure is demonstrated not only strengthen the material but also improve the ductility simultaneously. The harmonic structure and mechanical properties of titanium alloy， stainless steel， high speed steel/low carbon steel， cobalt based alloy and pure copper were analyzed. The key technical points for preparing the harmonic structure were reviewed， including initial powder， severe plastic deformation and hot consolidation.

Key words： sintering materials harmonic structure severe plastic deformation mechanical properties
