Abstract
Nickel-base superalloys are provided. In an embodiment, a nickel-base superalloy includes a concentration of large radius elements disposed in the gamma phase of the nickel-base superalloy in a range of from about 3.6 to about 6.7, by atomic percent and a concentration of large radius elements disposed in the gamma prime phase of the nickel-base superalloy in a range of from about 4.2 to about 7.0, by atomic percent. The nickel-base superalloy has a density of about 9.0 grams per centimeter3 or less.

A nickel-base superalloy having a gamma phase and a gamma prime phase, the nickel-base superalloy comprising:
- nickel;
- small radius elements selected from the group consisting of cobalt, aluminum, and chromium;
- and
- large radius elements selected from the group consisting of molybdenum, tungsten, rhenium, tantalum, hafnium, titanium, niobium, and precious metal elements, the precious metal elements selected from the group consisting of ruthenium, platinum, iridium and rhodium,
- wherein:
- a concentration of the large radius elements is disposed in the gamma phase of the nickel-base superalloy being in a range of from about 4.4 to about 6.7, by atomic percent,
- a concentration of the large radius elements is disposed in the gamma prime phase of the nickel-base superalloy being in a range of from about 4.2 to about 7.0, by atomic percent,
- about 66% of a total amount of molybdenum is partitioned into the gamma phase of the nickel-base superalloy and about 34% of the total amount of molybdenum is partitioned into the gamma prime phase of the nickel-base superalloy,
- about 37% of a total amount of tungsten is partitioned into the gamma phase of the nickel-base superalloy and about 63% of the total amount of tungsten is partitioned into the gamma prime phase of the nickel-base superalloy,
- about 84% of a total amount of rhenium is partitioned into the gamma phase of the nickel-base superalloy and about 16% of the total amount of rhenium is partitioned into the gamma prime phase of the nickel-base superalloy,
- about 10% of a total amount of tantalum, hafnium, titanium, and niobium is partitioned into the gamma phase of the nickel-base superalloy and about 90% of the total amount of tantalum, hafnium, titanium, and niobium is partitioned into the gamma prime phase of the nickel-base superalloy,
- about 46% of a total amount of the precious metal elements is partitioned into the gamma phase of the nickel-base superalloy and about 54% of the total amount of the precious metal elements is partitioned into the gamma prime phase of the nickel-base superalloy, and
- the nickel-base superalloy has a density of about 9.0 grams per centimeter3 or less.
