PROCESS FOR PRODUCING METALLIC MEMBER AND STRUCTURAL MEMBER

摘要

A process for metallic member production including the shot peening of a surface of a metallic material, in which iron adherent to the metallic-material surface is efficiently removed almost without causing the metallic material to suffer a dimensional change or surface shape roughening, and which imparts improved fatigue properties to a metallic member to be produced. A surface of a metallic material comprising a light alloy is bombarded with first particles having an average particle diameter of 0.1-5 mm and comprising iron as the main component. Successively, the surface of the metallic material is bombarded with second particles having an average particle diameter of 200 µm or smaller and containing substantially no iron.
