NICKEL-BASE WELD MATERIALS, PROCESSES OF USING, AND COMPONENTS FORMED THEREWITH

摘要

Nickel-base alloys suitable for use as a weld material to weld high- temperature components (10), such as turbine blades and vanes of gas turbine engines. The nickel-base alloys consist essentially of, by weight, 5 to 10 percent chromium, 3 to 14 percent cobalt, up to 4 percent molybdenum, 3 to 7 percent tungsten, 5 to 9 percent tantalum, 5 to 8 percent aluminum, 0.1 to 2 percent hafnium, 0.005 to 0.03 percent boron, up to 0.15 percent carbon, the balance being nickel and incidental impurities and/or residual elements. Welds (12) formed with the alloys are capable of exhibiting desirable levels of strength and oxidation resistance, while containing little if any rhenium.
