COMPOSITE STRUCTURE MATERIAL Russian patent published in 2011 - IPC C22C1/05 

FIELD: metallurgy.

SUBSTANCE: composite structure material consists of metal matrix, of powder additive corresponding to inter-metallide, steel or alloy, and nano-disperse powder corresponding to thermo-dynamic stable oxides, carbides, nitrides and borides of metals and/or non-metals resistant to components of structure material. Matrix and reinforcer consist of spherical granules of dimension 5-800 mcm, fraction composition of which is divided into granules from 1 to n-order, where n is general amount of fractions in material. Granules of the 1^st order have dimension d₁ and make the base of matrix with forming interstices wherein there are located granules of reinforcing additive from the 2^nd to (n-1) order. Their dimensions are distributed in correspondence with golden section of descending series of Fibonacci with ratio d_n/d_n-1 close or equal to 0.62. Non-disperse powder is located in left interstices of the matrix of the least dimension.

EFFECT: high strength, fatigue and heat resistant properties of material, good plasticity, high modulus of elasticity and lasting thermal stability.
