1. A method comprising:
subjecting atomized powders of a nickel-base alloy to a solution treatment; quenching the solution treated atomized powders so as to develop powders comprising particles having a thermally altered microstructure, wherein the thermally altered microstructure comprises gamma phase, gamma prime phase, gamma double prime phase, or combinations thereof; introducing a powder feedstock comprising the particles having the thermally altered microstructure into a cold-spray apparatus; and operating the cold-spray apparatus to deposit the feedstock.
