Improved high-temperature-strength nickel-base superalloy
Nickel-base superalloy has a strength of 20,000 psi at 2,200 degrees F, approximately double the strength of the strongest available cast nickel-base alloys. It is not subject to the formation of embrittling phases upon long time exposure at intermediate temperatures
High strength nickel base alloy, WAZ-16, for applications up to 2200 F
Alloy product is high strength, high temperature nickel base material with higher incipient melting temperature than all known nickel base alloys. It is microstructurally stable and has high impact resistance both before and after prolonged thermal exposure. It contains relatively few alloying constitutents and low content of expensive and rare metals
High strength nickel-base alloy with improved oxidation resistance up to 2200 degrees F
Modifying the chemistry of the NASA TAZ-8 alloy and utilizing vacuum melting techniques provides a high strength, workable nickel base superalloy with improved oxidation resistance for use up to 2200 degrees F
Nickel-base alloy containing Mo-W-Al-Cr- Ta-Zr-C-Nb-B Patent
Nickel base alloy with resistance to oxidation at high temperatures and superior stress-rupture propertie
Nickel base alloy
A nickel base superalloy for use at temperatures of 2000 F (1095 C) to 2200 F (1205 C) was developed for use as stator vane material in advanced gas turbine engines. The alloy has a nominal composition in weight percent of 16 tungsten, 7 aluminum, 1 molybdenum, 2 columbium, 0.3 zirconium, 0.2 carbon and the balance nickel
Cauchy horizon stability in self-similar collapse: scalar radiation
The stability of the Cauchy horizon in spherically symmetric self-similar
collapse is studied by determining the flux of scalar radiation impinging on
the horizon. This flux is found to be finite.Comment: 10 pages. To appear in Phys Rev
A nickel base alloy, NASA WAZ-16, with potential for gas turbine stator vane application
A nickel-base superalloy based on the nickel-aluminum-tungsten system designated WAZ-16 was developed for high strength in the 1095 C (2000 F) to 1205 C (2200 F) range. Its tensile strength at the latter temperature is approximately 186 MN/m2 (27,000 psi). The combination of properties of the alloy suggest that it has potential as a stator vane material in advanced gas turbine engines
