• HotRolling, ColdForming; Extrusion, and Forging ...

    In hotrolling, hotmolten steel is passed several times through pairs of rolls to achieve the desired profile. Most structural steel components such as IShape, LShape, etc. are hotrolled. Coldrolling can increase the material strength and improve the surface finish. Coldrollforming uses thin sheets of steel to form into various shape ...

  • A theory of the yielding and plastic flow of anisotropic ...

    The theory is applied to experiments of Körber Hoff (1928) on the necking under uniaxial tension of thin strips cut from rolled sheet. It is shown, in full agreement with experimental data, that there are generally two, equally possible, necking directions whose orientation depends on the angle between the strip axis and the rolling direction.
