摘要： A metal material comprises a Zn—Al—Sn based alloy (ZAS alloy) and Cu diffused in the alloy, wherein Cu is diffused into the inside of the alloy to a depth from the surface of 0.5 mm or more, the concentration of Cu decreases from the surface of the ZAS alloy towards the inside thereof, and there is present no specific interface between Cu and the ZAS alloy; and a method for producing the metal material involves applying, to the surface of the ZAS alloy, an agent comprising a solvent and, dispersed therein, a material containing Cu such as a Cu powder and a Cu—Mn alloy powder and preferably, dispersed or dissolved therein, a reducing agent capable of reducing an oxide film present on the surface of the ZAS alloy, and heating the ZAS alloy having the agent applied thereon, to thereby diffuse Cu into the alloy.

摘要： A mold for casting primarily of SMC420, wherein a cavity forming portion comprising maraging steel, which has the toughness and the resistance to heat shock superior to those of SMC420, is provided in a vertical wall heading for a cavity surface from a molten metal inlet and a portion nearest to the molten metal inlet in the cavity surface, which are portions suffering relatively large heat shock in the contact with a molten metal. Also provided is a method for providing the cavity forming portion, which comprises filling a concave portion of the mold with a molten metal prepared by melting a welding rod by arc welding, in other words, carrying out an overlaying welding, and then cooling and solidifying the molten metal.
