  • Patent number: 7934407
    Abstract: A process for producing a metallic component of a structural member or the like used in an aircraft or automobile or the like, the process including shot peening the surface of a metallic material, wherein the fatigue properties of the metallic material are improved with almost no variation in the surface roughness over the course of shot peening. Shot peening the metallic material surface uses a shot material having an average particle size of not more than 200 ?m, and the ratio of the surface roughness of the metallic material surface following the projection step relative to the surface roughness of the metallic material surface prior to the projection step is not less than 0.8 and not more than 1.5.
