    摘要： To provide a technique that reduces an amount of energy consumption at manufacture of a pipe material having a high strength and improves a recyclability of the manufactured pipe material.
    First, a long, solid raw material made of a steel material containing 0.05 to 0.25 weight% C is prepared. Subsequently, the prepared raw material is cut to form a solid billet. After that, the solid billet is processed into a hollow blank 920. Then, warm extrusion molding is performed on the hollow processed blank 920 to be molded in a tubular shape.

    摘要： This invention relates to a method producing a common rail excellent in fatigue strength from an inexpensive steel which uses as the material of the common rail a steel for high-strength liquid phase diffusion bonding having good toughness and fatigue strength, which steel contains, in mass%, C: 0.01 to 0.3%, Si: 0.01 to 0.5%, Mn: 0.01 to 3.0%, Cr: 1.0 to 12.0% and Mo: 0.1 to 2.0%, further contains, in mass%, V: 0.01 to 1.0%, B: 0.0003 to 0.01%, Ti: 0.01 to 0.05% and N: 0.001 to 0.01%, has P content limited to 0.03% or less, S content to 0.01% or less and O content to 0.01% or less, further has total content of grain boundary segregated embrittling elements As, Sn, Sb, Pb and Zn limited to 0.015% or less, and a balance of unavoidable impurities and Fe. The steel is used for liquid phase diffusion bonding. The production method uses a pulsed laser beam to perform laser-peening in the presence of a transparent liquid with respect to the vicinity of the boundary between the inner surface 21 of each branch hole 6 and the inner surface 22 of the rail hole 5, located at an opening peripheral zone of the branch hole 6. The surface layer of steel of the opening peripheral zone is thereafter removed.

    摘要： A method for manufacturing a metal structure (130) for use in a downhole assembly comprises plastically deforming at least a portion of the metal structure (130); and heating at least the deformed portion of the metal structure to a temperature below its critical and/or transformation temperature. An assembly for performing the method comprises a production fixture (370) configured to receive the metal structure (130), wherein the production fixture is adapted to undergo heating to a temperature below and/or up to the critical and/or transformation temperature of the metal structure. By heating at least the deformed portion of the metal structure to a temperature below its critical and/or transformation temperature, the metal structure may undergo stress relief, which may help prevent undesirable movement of deformed portion, e.g. collet fingers of a catching apparatus, against the direction of deformation after impact(s) and/or shock(s) from moving objects, in use.
