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. |
