A method is provided that includes depositing metal powder over a seed crystal having a predetermined primary orientation, scanning an initial pattern into the metal powder to melt or sinter the deposited metal powder, and re-scanning the initial pattern to re-melt the scanned metal powder and form an initial layer having the predetermined primary orientation. The method further includes depositing additional metal powder over the initial layer, scanning an additional pattern into the additional metal powder to melt or sinter at least a portion of the additional metal powder, re-scanning the additional pattern to re-melt a portion of the initial layer and the scanned deposited additional metal powder to form a successive layer having the predetermined primary orientation, and repeating the steps of depositing additional metal powder, scanning the additional pattern, and re-scanning the additional pattern, until a final shape of the component is achieved.

Method of fabricating turbine components for engines

Nickel-based superalloys, turbine blades, and methods of improving or repairing turbine engine components are included. A nickel-based superalloy includes, by weight, about 5% to about 12% cobalt, about 3% to about 10% chromium, about 5.5% to about 6.3% aluminum, about 5% to about 10% tantalum, about 3% to about 10% rhenium, about 2% to about 5% of one or more of elements selected from a group consisting of platinum, ruthenium, palladium, and iridium, about 0.1% to about 1.0% hafnium, about 0.01% to about 0.4% yttrium, about 0.01% to about 0.15% silicon, and a balance of nickel.

Nickel-based superalloys, turbine blades, and methods of improving or repairing turbine engine components

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 centimeteror less.
