Nickel-containing alloys, method of manufacture thereof and articles derived therefrom

A nickel-containing alloy comprising:

• about 1.6 to about 1.8 weight percent aluminum;
• about 2.2 to about 2.4 weight percent titanium;
• about 1.25 to 1.45 weight percent niobium;
• about 22 to about 23 weight percent chromium;
• about 18.5 to about 19.5 weight percent cobalt;
• about 0.08 to about 0.12 weight percent carbon;
• about 1.9 to about 2.1 weight percent tungsten;
• about 0.002 to about 0.006 weight percent boron;
• up to 0.01 weight percent zirconium;
• with the remainder being nickel.

A method for manufacturing an article, comprising:

• (a) casting an alloy into a mold, wherein the alloy comprises about 1.5 to about 4.5 weight percent aluminum;
• about 2.1 to about 4.5 weight percent titanium;
• about 0.8 to about 3 weight percent niobium;
• about 14 to about 24 weight percent chromium;
• about 10 to about 23 weight percent cobalt;
• about 1 to about 3 weight percent of an element selected from tungsten, rhenium, ruthenium, molybdenum, or a combination thereof;
• about 0.05 to about 0.2 weight percent of carbon;
• about 0.002 to about 0.012 weight percent of boron;
• and about 40 to about 70 weight percent nickel;
• and
• (b) solidifying the casting.
