EVOLUTION IN TEXTURE AND ITS THROUGH-THICKNESS VARIATIONS IN Al-Mg-Si-EXTRUSIONS: EXPERIMENTS AND MODELLING.
Through thickness variations of deformation texture in round profile extrusions of 6063-type aluminium alloy: Experiments, FEM and crystal plasticity modelling
Deformation and recrystallization microstructure and texture of symmetric and asymmetric extruded aluminium AA6063 flat profiles
Experimental Investigations and Numerical Simulations of Textures and Microstructures of Extruded Aluminum Alloys
An extrusion microstructure modelling framework applied to AlMgSi-extrusions
Coupled FEM and Alamel-type polycrystal plasticity modelling applied to extrusion of aluminium alloys
The evolution of deformation texture during an axisymmetric extrusion of an Al-Mg-Si aluminium alloy is simulated by coupled finite element method (FEM) and polycrystal plasticity modelling. The FEM-simulations provide spatial and temporal history of strain, strain-rate and temperature, i.e. the def...
Visual appearance characteristics of industrial aluminium surfaces
An experimental study has been performed on the interrelationship between visual appearance, surface topography and light scattering on AA6063-T6 aluminium extrusions etched to a depth of up to 700 μm. The topography was characterized by use of White Light Interferometry (WLI), and light scattering ...
Optimisation of flow balance and isothermal extrusion of aluminium using finite-element simulations
FEM simulations of temperature evolution in aluminum extrusion: Identification of numerical problems in Altair HyperXtrude
The aim of this paper is to study how to identify numerical problems causing artificial heat generation in the Altair HyperXtrude FEM software. This software has been used to model the three dimensional transient problem of hot aluminum extrusion in order to study the flow balance and temperature di...
