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, the nucleant material lowering the nucleation energy required to crystallize the metal alloy; blending the 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 sufficient to 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 metal alloy to recrystallize; forming a second layer of the blended mixture on the first layer; and repeating the subjecting and allowing steps on the second layer to form an additional portion of the metal alloy article.

Abstract: A Ni-based superalloy composition to be used for powder-based additive manufacturing (AM) technology, such as selective laser melting (SLM) or electron beam melting (EBM). The cracking susceptibility during an AM process is considerably reduced by controlling the amount of elements, especially Hf, that form low-melting eutectics.

Abstract: In a method for producing a mixture of a metallic matrix material and an additive, a metallic bulk material is molten in a multi-shaft screw machine in a heating zone thereof by means of an inductive heating device to form a metal matrix material. As the at least one housing portion of the housing of the multi-shaft screw machine is made of a non-magnetic and electrically non-conductive material at least partly in the heating zone, a high and efficient energy input for melting the metallic bulk material is achievable in a simple manner. The additive for producing the mixture is admixed to the metallic matrix material by means of treatment element shafts of the multi-shaft screw machine.

Abstract: This invention relates to metal composites and to metal-alloy composites. Metal-alloy composites of this invention comprise a metal alloy and layered inorganic nanostructures or nanoparticles such as nanotubes, nanoscrolls, spherical or quasi-spherical nanoparticles, nano-platelets or combinations thereof. Methods of producing the metal composites and the metal-alloy composites are demonstrated. The layered inorganic nanostructure serves as a strengthening phase. The layered inorganic nanostructure provides reinforcement to the metal alloy.

Abstract: A method for synthesizing a metal matrix nanocomposite (MMNC) is an in-situ synthesis technique for preparing a metal matrix with ceramic reinforcements dispersed homogenously therein. The method includes mixing a base metal matrix material with two or more ceramic-forming elements to form a mixture; blending the mixture; drying the mixture; ball milling the mixture with a plurality of milling balls to form a milled mixture; using induction heating to form a melt flow and induce electromagnetic forces; and initiating a plurality of stirring vortexes in the melt flow to form the metal matrix nanocomposite.
