Notes:
Thixo-extrusion processing could become an important technique to extend the range andcomplexity of extruded profiles. This work presents the results of thixo-extrusion process appliedon aluminium alloy and they were carried out with both computer numerical simulation andexperimental methods. The thixo-extrusion set-up was made. Backward extrusion tests wereparticularly studied and simulated using Forge 2005 software. The constitutive equation used forthese simulations is based on a micro-macro model for the semi-solid evolution. The constitutiveequation parameters were identified due to comparisons of the simulated load-displacementresponses with experimental ones for backward extrusion tests on 7075 semi-solid aluminium alloy,for different temperatures
