摘要： The present invention provides a method for a shot-peening processing that can process in one step and thus reduce operating costs and the cost of equipment while increasing the efficiency of the treatment in the peening processing while achieving a peening effect similar to the effect obtained by shot-peening processing a plural number of times, that is, deeply generating compressive residual stress far from the top surface while generating the peak value of the compressive residual stress on the top surface. This method is characterized by projecting, on a product to be subjected to peening, shot in which two or three kinds of particles, each having a different predetermined average particle diameter and having a predetermined average particle diameter ratio to one another, are combined in a predetermined weight ratio.

摘要： A method of so-called “ultrasonic” peening is described for peening large sized annular surfaces on thin parts. The method uses a microbead mist vibrated in a chamber with an opening so that the surface that is to be peened makes at least five movements past the opening of the peening chamber during peening so as to reduce deformation of the part.

摘要： The process for manufacturing a metallic component, such as a wheel part for the rolling system of a vehicle, which includes, in an initial stage, forming the component of a metallic material in a semi-solid state and having a thixotropic structure, and in a subsequent cold-treatment stage, cold-treating at least part of said component by blasting it with projectiles with a view to plastic deformation thereof. A wheel in which a metallic disk is welded to a wheel rim and in which the metallic disk is obtained by the manufacturing process.

摘要： Disclosed is a strength-enhancing apparatus for a metal part comprising a recovery mechanism for sucking powder flow dust generated from glass beads crushed on a surface of a gear in a chamber to recover it together with drainage, wherein the recovery mechanism includes a liquid-spouting means arranged on a ceiling in the chamber, for effecting showering for the whole interior of the chamber. Accordingly, it is possible to reliably recover the mist containing the powder flow dust floating in the chamber, and it is possible to reliably avoid adhesion and accumulation of the powder flow dust.

摘要： A steel pipe is provided which is excellent in resistance to outer surface stress corrosion cracking (SCC) when used for a pipeline without impairing the fundamental requirement for the steel as a pipeline. The steel pipe has a surface adjusted to have a mean line roughness Ra of up to 7 &mgr;m and a maximum height Rmax of up to 50 &mgr;m. The surface is adjusted by sand blasting to have this roughness.
