ALLOY ON NIOBIUM BASE Russian patent published in 2009 - IPC C22C27/02 

FIELD: metallurgy.

SUBSTANCE: invention refers to metallurgy and can be implemented for fabricating items operating under conditions of mechanical stresses at higher temperatures. To upgrade strength of alloy under conditions of higher temperatures the alloy has the following composition, wt %: molybdenum 8.5-9.5; zirconium 2.0-3.0; carbon 0.01-0.03; nitrogen 0.05-0.1; lanthanum 0.1-0.15; rhenium 1.3-1.7; boron 0.005-0.01; niobium- the rest. Ultimate stress of alloy at 1200°C is 23-24 kg/mm².

EFFECT: upgraded strength of alloy.
