The accumulative roll bonding (ARB) as a severe plastic deformation (SPD) procedure aimed at enhancing the mechanical properties of metals and alloys. In the present study, a new slab method is proposed for estimating the forming stress field for cold extrusion of metals cross the alumina interlayer powder particles by accumulative roll bonding process. Plastic deformation behavior of the metal...
the current study conducted a finite element (fe) and experimental investigation on tubular channel angular pressing as a noble severe plastic deformation technique for producing ultrafine grained and nanostructure tubular components. to examine the effects of the tcap process on the strain distribution and deformation behavior, fe simulations were employed. the fe results demonstrated that equ...

Tubular channel angular pressing (TCAP) is a recently invented novel severe plastic deformation technique for producing UFG tubes. Plastic deformation analysis using the finite element method (FEM) was carried out to investigate the effects of trapezoidal channel geometry on strain inhomogeneity index (SII), strain level and required load compared to previously used channel geometries. The resu...
one of the most common methods for production of ultra fine grained materials is severe plastic deformation (spd). in this study, constrained groove pressing (cgp) and high pressure torsion (hpt) processes as effective methods of severe plastic deformation for the strain imposed on the pure copper were used. this paper presents the results of an experimental research, to review the influence of...
