Strained State of Porous Preforms during Hot Forging in a Die with a Cone-Shaped Flash Gutter

Coordinate grids are used to understand how the strained state of porous preforms evolves during hot forging in a semi-closed die with a cone-shaped flash gutter. The nature of strain tensors and the irregularity of porosity distribution over the forged pieces at various forging stages are establish...

Zusammenfassung:Coordinate grids are used to understand how the strained state of porous preforms evolves during hot forging in a semi-closed die with a cone-shaped flash gutter. The nature of strain tensors and the irregularity of porosity distribution over the forged pieces at various forging stages are established.
