Texture evolution in commercially pure titanium deformed by equal-channel angular
pressing (ECAP) and extrusion with forward–backward rotating die (KoBo) is studied both …

The present work aims to elucidate the role of microstructural changes induced by the
extrusion with a forward backward oscillating die, thus verifying a novel approach to …

Microstructure evolution, phase development and mechanical property of AZ80 alloy cup
with various processing temperatures (573 K, 613 K, 653 K) and rotating revolutions (N= 0 …

Torsion extrusion (TE) is a severe plastic deformation (SPD) technique with the potential to
be used for the preparation of large bulk materials with enhanced mechanical properties …

Plastic flow of hollow cylinders under combining axial compression with torsion was
examined in upsetting and in lateral extrusion. The hollow cylinders with initial height/outer …

Torsional oscillation with a maximum frequency of 1.5 Hz was superposed with axial forging
load to reduce the axial forging load in cold upsetting process. A cylindrical aluminum …

The effects commonly related with deformation caused by proportional and non-proportional
loading types were identified experimentally. In the case of non-proportional cyclic loading …

Numerical simulations of the kOBO extrusion process are presented in this paper. the
coupled thermomechanical Eulerian-Lagrangian approach was applied for the three …

The precipitation hardened AA 6013 aluminium alloy was extruded by means of the KoBo
extrusion method with an oscillating die. In the presented paper, the influence of two …

To ensure realistic results in modelling processes for analysing strains in material using
finite element (FE) models, it is essential to have a model of the material that is as close to …
