Purpose of the development: Designed for gas turbine engine blades (TBG).

Recommended application field: Areas of application: - Production of gas-turbine operating at high temperatures, mechanical stress and corrosion effects; - Aerospace engineering; - Nuclear energy; - Shipbuilding; - Power engineering.

Technical characteristic: Technical characteristics: - Parameter of the dendritic cell: - In the cast state - 120 - 180 microns; - After extrusion - 60 - 90 microns; - Morphology hardening gamma phase: - In the cast state - kuboidnye particle size of 0.3 - 0.6 microns; - After plastic deformation - particles or globular form kuboidnoy 0.05 - 0.2 microns; - Strength - ~ 150 kg/mm2; - Long-term heat resistance increased 1.5 - 2 times.

Advantages over analogues: Increased resource work, increasing the strength properties of heat resistance prolonged growth, increasing the bond strength of the blades with a protective coating.

The development stage readiness: Introduced in production

Description of the development:
()
Blanks are made of single-crystal nickel-based alloys (Ni-W) and high-temperature single-crystal nickel superalloys . Formation occurs through the process of harvesting high-gradient directional crystallization ( VGNK ), which allows a uniform and finely oriented along the direction of the heat sink microstructure workpiece. Perfect single crystal microstructure of nickel superalloys able to deform plastically at elevated temperatures and under certain conditions, the nanostructure is formed . The technology allows to produce blanks for the entire range of existing working gas turbine engine blades .
