Abstract
Disclosed are methods and apparatuses for processing a powder alloy to improve its microstructure. The methods for processing the powder alloy can include introducing the powder alloy into a powder vessel having an inert atmosphere, uniformly heat treating the powder alloy inside the powder vessel at its solutionizing temperature, and cooling the heat treated powder alloy at a rate of at least 5° C./s to form treated particles. The treated particles obtained from the methods and apparatuses disclosed herein can be used in any suitable manufacturing process, such as in cold gas dynamic spray.
