MOLYBDENUM BASED HEAT RESISTANT ALLOY Russian patent published in 2022 - IPC C22C27/04 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy, namely to high-strength molybdenum-based heat-resistant alloys, and can be used for the manufacture of products subjected to high temperatures during operation in a vacuum or oxygen-free environment, in the electronic, electrical industries industry, nuclear power, aviation and space technology. The heat-resistant alloy based on molybdenum contains, wt.%: tantalum 0.2-0.9, tungsten 0.1-0.9, at least one of the group of elements: iron, cobalt, nickel in the amount of 0.01-0, 03, zirconium 0.1-0.3, hafnium 0.2-0.9, carbon 0.01-0.05, oxygen not more than 0.003, molybdenum - the rest.

EFFECT: alloy is characterized by high strength at temperatures up to 1600°C while maintaining high ductility at room temperature.
