Finite element modeling of Conform-HPTE process for a continuous severe plastic deformation path

, 2020
A novel continuous severe plastic deformation (SPD) approach was proposed by combining continuous extrusion forming (Conform) with high pressure torsion extrusion (HPTE), which is called Conform-HPTE process.

Processing Metals by Severe Plastic Deformation

Solid State Phenomena, 2005
Severe plastic deformation (SPD) is used to convert traditional coarse grain metals and alloys into ultrafine-grained (UFG) materials. UFG materials possess a number of improved mechanical and physical properties which destine them for a wide commercial use.

Texture Formation during Severe Plastic Deformation

Materials Science Forum, 2005
The paper represents results of computer modeling of texture formation in pure copper subjected to severe plastic deformation (SPD) realized by equal channel angular pressing (ECAP). Several polycrystalline models, namely the Taylor model, Sachs model, and self-consistent viscous plastic (VPSC) model, were applied and their predictions of texture ...

Equivalent Strains in Severe Plastic Deformation

Advanced Engineering Materials, 2003
AbstractThe concept of equivalent plastic strain is discussed. Definitions may be based on kinematic arguments (like change of geometry) or on equivalence of plastic work. Complications arise when strain is accumulated in increments with variable strain path.

Benefits of pattern formation by severe plastic deformation

Applied Materials Today, 2019
Nature abounds with patterns of various kinds. Possible cellular, helical, wavy, fold-like, fractal, and other structures provide natural objects with distinctive, and often unique, physico-mechanical properties.

Mechanical Alloying and Severe Plastic Deformation

2007
Recently developed methods for materials processing, such as mechanical alloying, cryomilling, friction stir processing, equal-channel angular pressing, and high-pressure torsion, are reviewed in the present chapter. Over the last two decades, there has been increasing interest on the synthesis of advanced materials using mechanical alloying, and ...
