METAL MOLDED PRODUCT AND METAL POWDER FOR METAL MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide a metal molded product that is free from internal defects and is excellent in mechanical characteristics such as strength, ductility and the like and functional characteristics such as abrasion resistance, corrosion resistance and the like and to provide a metal powder for a metal molded product for use in the metal molded product.SOLUTION: The metal molded product is formed of an alloy including a main metal element and an additive element and having a ratio 100(a-b)/b of an atomic radius a of the additive element to an atomic radius b of the main metal element in a range of -30% to +30% and is produced by laminating a raw material metal powder by a lamination method. When the additive element is partially solid-dissolved in the main elemental metal, the ratio 100(a-b)/b is permitted to be adjusted outside the range of -30% to +30%.SELECTED DRAWING: Figure 1
