FIBROUS COMPOSITE MATERIAL WITH MATRIX BASED ON NIOBIUM Russian patent published in 2015 - IPC C22C27/02 C22C49/10 C22C101/04 C22C47/14

Abstract RU 2568407 C1

FIELD: metallurgy.

SUBSTANCE: fibrous composite material contains matrix and reinforcing monocrystal fibres of aluminium oxide. Matrix out of niobium or niobium-based alloy is made by high energy grinding of niobium powder or mixture of input powders of alloy based on niobium. Monocrystalline fibres of aluminium oxide have diameter from 50 to 500 mcm, and content from 10 to 60 vol %.

EFFECT: composite material is characterized by high strength at room and increased temperatures, and maximum work temperature at least 1700 degrees.
