Abstract: An additive manufacturing method of producing a metal alloy article may involve: Providing a supply of a metal alloy in powder form; providing a supply of a nucleant material, thenucleant material lowering the nucleation energy required to crystallize the metal alloy; blendingthe supply of metal alloy powder and nucleant material to form a blended mixture; forming the blended mixture into a first layer; subjecting at least a portion of the first layer to energy sufficientto raise the temperature of the first layer to at least the liquidus temperature of the metal alloy;allowing at least a portion of the first layer to cool to a temperature sufficient to allow the metalalloy to recrystallize; forming a second layer of the blended mixture on the first layer; and repeatingthe subjecting and allowing steps on the second layer to form an additional portion of the metal alloy article.

Abstract: An additive manufacturing method may involve: Providing a first and a second material, the second material capable of reacting with the first material to form a reaction product; forming at least the first material into a first layer; subjecting at least a portion of the first layer to energy in the presence of the second material, the energy being sufficient to initiate a reaction between the first and second materials to form a portion of the article, the portion of the article comprising the reaction product; forming a second layer of at least the first material on the first layer; and subjecting at least a portion of the second layer to energy in the presence of the second material, the energy being sufficient to initiate a reaction between the first and second materials to form an additional portion of the article.
