Thermo-mechanical modelling of indirect extrusion process for magnesium alloys [PDF]
International Journal of Material Forming, 2009 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

Materials, 2023 Avoiding loose powders and resins, material extrusion additive manufacturing is a powerful technique to produce near-net shape parts, being a cheap and safe alternative for developing complex industrial-grade products. Filaments embedded with a high packing density of metallic or ceramic granules are being increasingly used, resulting in almost fully ...

Modelling of Thermo-Mechanical Behaviour of Magnesium Alloys during Indirect Extrusion [PDF]
Key Engineering Materials, 2009 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.

A study on surface cracking in extrusion of aluminium alloy AA2014 [PDF]
, 2004 Surface cracking is generally recognised as one of the main defects occurring during the process of aluminium extrusion, especially in the case of the so called hard aluminium alloys.
