NICKEL-BASED SUPERALLOYS AND ARTICLES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17737458 titled 'NICKEL-BASED SUPERALLOYS AND ARTICLES
Simplified Explanation
- The abstract describes a nickel-based superalloy composition that has specific weight percentages of various elements such as aluminum, tantalum, chromium, tungsten, molybdenum, rhenium, cobalt, hafnium, carbon, and boron. - This composition has been found to have a rupture life of more than 40 hours at a temperature of 982.2° C and a stress level of 40 ksi. - Additionally, the composition exhibits corrosion resistance of less than 50.8 μm attack after a 940-hour burner rig test at a temperature of 926.7° C. - The abstract also mentions that components can be formed from this composition.
Original Abstract Submitted
A nickel-based superalloy composition is provided that includes 6.1 wt. % to 6.6 wt. % aluminum; 5.6 wt. % to 6.6 wt. % tantalum; 9.0 wt. % to 11.0 wt. % chromium; 5.5 wt % to 6.2 wt. % tungsten; 1.1 wt. % to 1.4 wt % molybdenum; 2.0 wt. % to 2.6 wt % rhenium; 5.5 wt. % to 10.0 wt % cobalt; 0.2 wt % to 0.5 wt % hafnium; up to 0.05 wt % carbon; 0.002 wt % to 0.01 wt % boron; and a balance of nickel and incidental impurities, wherein the composition exhibits a rupture life that is greater than 40 hours at 982.2° C. and 40 ksi, and wherein the composition exhibits a corrosion resistance of less than 50.8 μm attack at 926.7° C. after a 940 hour burner rig test. Components are also provided formed from the composition.
