金属粉末材料の製造方法
Document Type and Number:
Japanese Patent JP7249811
Kind Code:
B2
Abstract:
To provide a method for producing a metal powder material capable of producing a metal powder material suitable for producing a three-dimensional molding in a lamination molding process.SOLUTION: A raw material production step of producing a raw material body made of metal grains by an atomization process and a grain cracking step of mechanically dissolving the coagulation of the metal grains in the raw material body are performed in this order to produce a metal powder material. In the grain cracking step, the shear of the coagulated body of the metal grains is performed by an air flow, and shear force is applied to the coagulated body by a forced vortex.SELECTED DRAWING: Figure 5
