Formability of tailored blanks
Journal of Materials Processing Technology, 1997Abstract Toyota has applied laser-welded tailored blanks for stamping side panel, door inner, front side member and many other auto body panels. Judgment on the formability in actual panel stamping is difficult, because the behavior in press forming of the portion near the weld lines differs from the base material. We have obtained by experiments the

The plastic deformation of a sheet metal into complicated shapes is brought about by the imposition of a combination of stresses. Complex stamping requires varying amount of stretching and drawing, to which bending and buckling are added. Traditionally, prediction of forming behaviour of materials are based on tensile test data, simulative tests and ...

On Formability of MoNiCr Alloy
Advanced Materials Research, 2011The paper deals with recrystallization conditions monitoring for MoNiCr nickel superalloy. The alloy is determined for modern concepts of nuclear reactors in which molten fluoride salts are used in the primary and/or secondary circuit as coolants. It represents a material with high corrosion resistance against fluoride salts and it has very good creep ...

The chapter presents synthetically the most recent models of the anisotropic plastic behavior. The first section gives an overview of the classical models, In the next step, the discussion is focused on the anisotropic formulations developed on the basis of the theories of linear transformations and tensor representations, respectively.

Atlas of Formability: Waspaloy
1992Abstract : In this investigation, flow behavior of Waspaloy alloy was studied by conducting compression tests over a wide range of temperatures and strain rates. Constitutive relations were determined from the flow behavior, and a dynamic material modeling was conducted on this alloy.
