METHOD OF PRODUCING NANOSTRUCTURED STRUCTURAL MATERIAL WITH 3D NANOSTRUCTURE Russian patent published in 2011 - IPC B22F3/00 B82B3/00 

FIELD: process engineering.

SUBSTANCE: invention relates to powder metallurgy, particularly, to production of heat-resistant nanostructured structural material by granulation metallurgy. Proposed method comprises mixing components containing copper base and carbon nanotubes, a nanostructured material, and compacting produced mix at appropriate pressure and temperature. Prior to compacting, said mix is placed in capsule for mix to be compacted at 0.7-0.95 of copper base melting temperature and 1100-1500 atm for 2-5 hours. In mixing said component, they activated by straining in ball planet mill or by adding surfactants. Besides, prepared mix is subjected to pre-compaction at room temperature at 0.1-0.5% of modulus of elongation.

EFFECT: structural material with good soldering and welding properties and higher heat resistance.
