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 ...

Grain refinement and weak-textured structures based on the dynamic recrystallization of Mg–9.80Gd–3.78Y–1.12Sm–0.48Zr alloy

Journal of Magnesium and Alloys, 2021
We utilized electron backscatter diffraction to investigate the microstructure evolutions of a newly developed magnesium-rare earth alloy (Mg–9.80Gd–3.78Y–1.12Sm–0.48Zr) during instantaneous hot indirect extrusion. An equiaxed fine-grained (average grain

Microstructures and mechanical properties of Mg–6Zn–1Y–0.85Zr alloy prepared at different extrusion temperatures and speeds

Journal of Materials Research and Technology, 2022
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,

In-Depth Comparison of an Industrially Extruded Powder and Ingot Al Alloys

Metals, 2020
An industrial press was used to consolidate compacted aluminum powder with a nominal diameter in the range of 1 µm. Direct and indirect hot-extrusion processes were used, and suitable process parameters were determined from heating conditions, ram speeds
