  • Method of molding anisotropic composite material and die using anisotropic composite material
    Patent number: 11565323
    Abstract: Provided is a method of molding a composite material by laser metal deposition in which a powder metal material is irradiated with a laser beam while supplying the powder metal material onto a surface of a base material, in which the powder metal material is a mixed powder of an Fe alloy powder and a Cu powder, and a mixing ratio of the Fe alloy powder and the Cu powder is 15% or more and 30% or less by weight % of the Cu powder, and in which the composite material having anisotropy is molded by setting energy of the laser beam to be 9 KJ/g or more and 10 KJ/g or less in a mixed powder ratio.
    Type: Grant
