METHOD OF MAKING 3D COMPLEX-SHAPE NANOSTRUCTURED STRUCTURAL AND FUNCTIONAL MATERIALS Russian patent published in 2014 - IPC B22F3/02 B82Y40/00

Abstract RU 2508961 C2

FIELD: process engineering.

SUBSTANCE: invention relates to powder metallurgy, particularly, to production of nano-structured materials. Porous metal-matrix base is formed by sintering polymorphous powders of 1-10 mcm dispersion under conditions of free filling. Nanopowder of dispersion 10^-4-10^-6 mcm is added to said base heated to 0.4 of base material fusion point. Thereafter, compaction is performed at strain corresponding to superplasticity state.

EFFECT: higher physical and mechanical properties, efficient compaction, expanded processing performances.
