Method of shot peening processing and article processed thereby, and peening material and use thereof |
摘要 |
This invention provides a method for the treatment of shot peening by which a high residual compressive-stress can be given, while having the surface roughness of the treated article be low even when a metal substance with a high hardness is used. That is to say, this invention is related to a method for the treatment of shot peening wherein a peening material having a Vickers hardness (Hv) in the range of 900-1100 and a Young's modulus of 200,000 MPa or less, is used, and wherein a treated article is obtained by such a method that has a maximum residual compressive-stress of 1600 MPa or more and a surface roughness of 5 microns or less.
