Numerical modelling of the aluminium extrusion process [PDF]
The extrusion of aluminium alloys involves the shaping of the product from an homogenised billet into a complex shape. In addition the properties of the extrudate are closely related to the processing parameters (temperature, stain rate, and material ...

Microstructure and mechanical properties of moderate-speed extrudable Mg-Gd-Sm-Zr alloy
Extrusion Mg-Gd based alloy has the excellent mechanical properties, but usually at the sacrifice of productivity. In this paper, we designed a Mg-10Gd-1Sm-0.5Zr alloy, and have successfully extruded it with a die-exit speed of 3.2 m min ^−1 , and the ...

Numerical modelling of the aluminium extrusion process and comparison with results obtained from industrially extruded complex sections. [PDF]
This thesis reports the analysis of extruded products by Forge2009® and EBSD produced by the investigator in the BOAL plant. The 3D FEM module was used to study the required load, the temperature evolution, surface formation of the extrudate and material

The influence of extrusion temperature and speed on the microstructures and mechanical properties of the as-extruded Mg–6Zn–1Y–0.85Zr (ZWK610) alloy was inquired by indirect extrusion at three ram speeds (1, 3 and 6 mm/s) and extruding temperatures (250,

Thermo-mechanical modelling of indirect extrusion process for magnesium alloys [PDF]
The complexity of deformation phenomena observed in magnesium and its alloys originates from its hexagonal closed packed crystallographic structure. Mechanical anisotropy and asymmetry in tension-compression are hence observed. A phenomenological model derived by Cazacu and Barlat accounts for the respective phenomena. However, the capabilities of this

Modelling of Thermo-Mechanical Behaviour of Magnesium Alloys during Indirect Extrusion [PDF]
A yield function for hexagonal closed packed (hcp) metals was modified with respect to strain rate and temperature and developed to capture the material behaviour during extrusion. Magnesium alloy ZEK100 was extruded indirectly at 300°C into a round bar.

AbstractPurposeThis study's goal is to propose a straightforward classification system based on the MEI (Meniscal Extrusion Index), a measure of meniscal extrusion, that relates to various meniscal lesion patterns and has clinical and biomechanical significance.
