摘要： A method of recovering rhenium from rhenium-containing superalloy scrap is provided. The superalloy is usually a nickel-based superalloy. The method includes the steps of forming an oxidation feedstock of flaky morphology of the superalloy scrap, and oxidizing the oxidation feedstock to convert rhenium into a volatile rhenium oxide. The flaky morphology of the oxidation feedstock is achieved by increasing the surface area of the superalloy scrap.

摘要： A nickel-based superalloy composition includes from about 5 to about 7 wt % aluminum, from about 4 to about 8 wt % tantalum, from about 3 to about 8 wt % chromium, from about 3 to about 7 wt % tungsten, from 1 to about 5 wt % molybdenum, from 1.5 to about 5 wt % rhenium, from 5 to about 14 wt % cobalt, from about 0 to about 1 wt % hafnium, from about 0.01 to about 0.03 wt % carbon, from about 0.002 to about 0.006 wt % boron, and balance nickel and incidental impurities. The composition may exhibit a sustained peak low cycle fatigue life at 1800° F./45 ksi of at least about 4000 cycles. The nickel-based superalloy composition may be used in single-crystal or directionally solidified superalloy articles, such as a blade, nozzle, a shroud, a splash plate, and a combustor of a gas turbine engine.
