Abstract
A method of recycling a structure or at least a portion thereof, and component for an aircraft or spacecraft. The structure comprises components connected to each other and each made from a metal alloy. The method includes producing, at least from a plurality of the components, including components made from at least two different metal alloys, a powder adapted to being used as a starting material in an additive manufacturing process. Also, a component for an aircraft or spacecraft, made using additive manufacturing, the component being produced a powder obtained in accordance with the method.
Claims19
A method of recycling a structure, or at least a portion thereof, wherein the structure comprises components connected to each other and each made from a metal alloy, wherein the method comprises:
- producing, at least from material of a plurality of components including components made from at least two different metal alloys, a powder configured to be utilized as a starting material in an additive manufacturing process, wherein producing the powder comprises:
- melting the material of the plurality of components to form a homogeneous melt;
- melt atomizing the homogenous melt in order to obtain the powder;
- and
- nano-decorating the powder with at least one additive.
A method of recycling a structure, or at least a portion thereof, wherein the structure comprises components connected to each other and each made from an aluminum alloy, wherein the method comprises:
- producing, at least from material of a plurality of components including components made from at least two different aluminum alloys, a powder configured to be utilized as a starting material in an additive manufacturing process;
- wherein the additive manufacturing process comprises locally melting the powder as part of a laser powder bed fusion process to form a melt and cooling the melt resulting therefrom at a cooling rate of at least 10,000 Kelvin per second;
- wherein producing the powder comprises nano-decorating the powder with at least one additive which is an additive capable of acting as a grain refiner and nucleating agent, the additive being a fine powder nano-additive comprising particles having a particle size of <1000 nm.
