Inconel 718 is a precipitation-hardening alloy, with a typical heat treatment consisting of solution annealing before a two-stage ageing process. Depending on the heat treatment procedure, strength or ductility can be enhanced, typically at the cost of the other. This study aims to determine a heat ...

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 ...

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...

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...
