ABSTRACT:
A process for producing a metallic component that includes shot peening the surface of a metallic material, wherein almost no dimensional change or roughening of the surface profile of the metallic material occurs, the iron fraction adhered to the surface of the metallic material is removed efficiently, and the fatigue properties of the produced metallic component are improved. First particles containing iron as the main component and having an average particle size of not less than 0.1 mm and not more than 5 mm are projected onto the surface of a metallic material containing a lightweight alloy, and second particles containing essentially no iron and having an average particle size of not more than 200 μm are then projected onto the surface of the metallic material.
