Abstract

An alloy that may include nickel, aluminum from 4.8 wt. % to 5.15 wt. %; cobalt from 18 wt. % to 19 wt. %, chromium from 11.9 wt. % to 12.9 wt. %, molybdenum from 2.8 wt. % to 3.6 wt. %, and niobium from 0.05 wt. % to 0.1 wt. %. The alloy may further include tungsten from 0.05 wt. % to 0.1 wt. %. The alloy may further include tantalum from 0.05 wt. % to 0.1 wt. %.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A nickel alloy, comprising:
 nickel;   aluminum from 4.8 wt. % to 5.15 wt. %;   cobalt from 18 wt. % to 19 wt. %;   chromium from 11.9 wt. % to 12.9 wt. %;   molybdenum from 2.8 wt. % to 3.6 wt. %; and   niobium from 0.05 wt. % to 0.1 wt. %.   
     
     
         2 . The nickel alloy of  claim 1 , further comprising tungsten from 0.05 wt. % to 0.1 wt. %. 
     
     
         3 . The nickel alloy of  claim 1 , further comprising tantalum from 0.05 wt. % to 0.1 wt. %. 
     
     
         4 . The nickel alloy of  claim 2 , further comprising tantalum from 0.05 wt. % to 0.1 wt. %. 
     
     
         5 . The nickel alloy of  claim 2 , wherein the ratio of tungsten to niobium is between 1:1 and 1:3. 
     
     
         6 . The nickel alloy of  claim 3 , wherein the ratio of tantalum to niobium is between 1:1 and 1:3. 
     
     
         7 . The nickel alloy of  claim 4 , wherein the ratio of tungsten to tantalum is between 1:1 and 1:3. 
     
     
         8 . The nickel alloy of  claim 4 , wherein the ratio of tungsten to niobium is between 1:1 and 1:3. 
     
     
         9 . The nickel alloy of  claim 4 , wherein the ratio of tantalum to niobium is between 1:1 and 1:3. 
     
     
         10 . The nickel alloy of  claim 4 , wherein the niobium is present at 0.1 wt. %. 
     
     
         11 . The nickel alloy of  claim 10 , wherein the tantalum is present at 0.1 wt. %. 
     
     
         12 . The nickel alloy of  claim 11 , wherein the tungsten is present at 0.1 wt. %. 
     
     
         13 . The nickel alloy of  claim 12 , further comprising titanium from 4.15 wt. % to 4.5 wt. %. 
     
     
         14 . A nickel alloy, comprising:
 nickel;   aluminum from 4.8 wt. % to 5.15 wt. %;   cobalt from 18 wt. % to 19 wt. %;   chromium from 11.9 wt. % to 12.9 wt. %;   molybdenum from 2.8 wt. % to 3.6 wt. %; and   tungsten from 0.05 wt. % to 0.1 wt. %.   
     
     
         15 . The nickel alloy of  claim 14 , further comprising tantalum from 0.05 wt. % to 0.1 wt. %. 
     
     
         16 . The nickel alloy of  claim 15 , wherein the ratio of tungsten to tantalum is between 1:1 and 1:3. 
     
     
         17 . A nickel alloy, comprising:
 nickel;   aluminum from 4.8 wt. % to 5.15 wt. %;   cobalt from 18 wt. % to 19 wt. %;   chromium from 11.9 wt. % to 12.9 wt. %;   molybdenum from 2.8 wt. % to 3.6 wt. %; and   tantalum from 0.05 wt. % to 0.1 wt. %.   
     
     
         18 . The nickel alloy of  claim 17 , further comprising niobium from 0.05 wt. % to 0.1 wt. %. 
     
     
         19 . The nickel alloy of  claim 19 , wherein the ratio of tantalum to niobium is between 1:1 and 1:3. 
     
     
         20 . An aircraft component comprised from the nickel alloy of  claim 1 .
