Abstract: Single crystal superalloy castings are described which have excellent oxidation resistance. The oxidation resistance is due to the presence of small but effective amounts of magnesium in the casting. Single crystal castings containing magnesium in the range of 5-200 parts per million, by weight, are described. Up to 100 % of the magnesium could be substituted by an equal atomic percent of calcium. The superalloy further consists essentially of, by weight percent, 1-12 chromium, 2-12 cobalt, 0-2.5 molybdenum, 3-10 tungsten, 0-8 rhenium, 2.5-13 tantalum, 0-2 titanium, 4.5-6.5 aluminum, 0-0.5 hafnium, 0-0.1 carbon, 0.0005-0.0200 magnesium, remainder nickel.

Abstract: High modulus turbine shafts and high modulus cylindrical articles are described as are the process parameters for producing these shafts and cylindrical articles. The shafts/articles have a high Young's modulus as a result of having high modulus crystal texture along the longitudinal axis of the shaft/article. The shafts are produced from directionally solidified seeded single crystal cylinders that are axisymmetrically hot worked before a limited recrystallization process is carried out at a temperature below the recrystallization temperature of the alloy. The disclosed process produces an intense singular texture and results in shaft or cylindrical article with a Young's modulus that is at least 40% greater than that of conventional nickel or iron alloys or conventional steels.
