  • Publication number: 20230143183
    Abstract: An object of the present invention is to provide an additive manufactured object which is free of solidification cracking due to, e.g., heat shrinkage during additive manufacturing of an aluminum alloy; which is free of anisotropy in strength, and has high strength and ductility. An aluminum alloy powder for additive manufacturing includes aluminum alloy particles in which not less than 0.01% by mass and not more than 1% by mass of a grain refiner is trapped. This grain refiner is at least one selected from the borides and carbides of group 4 elements.

    Abstract: The present invention provides a robust metal lamination-shaped object containing aluminum and having no defect. A metal powder used for forming this metal lamination-shaped object is an aluminum-based powder having a volume-based 50% particle diameter larger than or equal to 10 ?m and smaller than 100 ?m when a particle diameter distribution is measured by a laser diffraction-scattering method, a specific surface area smaller than or equal to 0.5 m2/g, and an oxygen amount larger than or equal to 3 mg/m2 and less than or equal to 10 mg/m2 per unit surface area. A relationship between a hydrogen amount (X ml in standard state) per 100 g of the aluminum-based powder and a specific surface area (Y m2/g), and a relationship between the hydrogen amount (X ml in standard state) and an oxygen amount (Z wt %), are respectively in accordance with formulas: X/Y<151 and Z/X>0.0022.
