HEAT-RESISTANT WELDED COBALT-BASED ALLOY AND ARTICLE MADE THEREFROM Russian patent published in 2016 - IPC C22C19/07 C22C19/05 C22C30/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy of heat-resistant welded wrought alloys and items made from said alloys, and can be used in making components of a combustion chamber, nozzle and other units of gas turbine engines and plants, operating to temperature of 1,250 °C. Heat-resistant welded cobalt-based alloy contains, wt%: chrome 20.0-28.0; tungsten 0.1-10.4; molybdenum 0.1-12.0; titanium 1.0-4.0; carbon 0.02-0.25; tantalum 1.0-4.0 or niobium 0.3-2.0; hafnium or zirconium 0.1-2.0; magnesium 0.002-0.3; lanthanum 0.002-0.1; boron 0.003-0.05; nickel 20-40; silicon 0.001-0.2; cobalt - balance.

EFFECT: alloy is characterised by increased values of short-term strength at room temperature and heat resistance of alloy.
