The microstructure of 6xxx aluminum alloys deeply affects mechanical, crash, corrosion and
aesthetic properties of extruded profiles. Companies, especially in the transportation sector …

Relatively low levels of inter-pass deformation have been found to be very effective in
refining the coarse columnar grain structures normally seen in Ti-6Al-4V components, built …

The thermal control and the maintenance of a uniform temperature in the extrusion process
of aluminum alloys is a crucial task in order to generate sound profiles with high press …

Charge welds occur in billet-to-billet extrusion processes due to the transition between
successive billets. The material in this transition zone is typically characterized by …

Radial-shear rolling (RSR) of titanium alloy billets was realized in a three-high rolling mill.
Experimental rolling was simulated using DEFORM software. The purpose was to reveal …

In the context of aluminum alloy extrusion, the presence of the skin contamination defect
imposes the scrap of the contaminated profile length due to its lower mechanical properties …

Hollow tubes are generally manufactured using porthole die extrusion. A finite element
software QForm is used to analyze the material flow of aluminum alloy A6061 tubes inside a …

This study aims to provide new insights into the governing mechanisms of material property
evolution within the charge weld zone in the hot extrusion process of aluminum profiles. A …

Present work examines and validates the novel numerical scheme to calculate the velocity,
stress, strain, pressure and strain rate fields of metal plastic flow in direct extrusion …

Comparisons of FVM and Forge 2008 codes presented in ICEB 2015 suggested that solid
metal extrusion can be modelled by FVM. Present work aim to validate FVM by comparisons …
