A NICKEL-BASE ALLOY, NASA WAZ-16, WITH POTENTIAL FOR GAS TURBINE STATOR VANE APPLICATION

摘要

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.
