Microstructure and mechanical properties of binary Mg–Sn alloys subjected to indirect extrusion
Materials Science and Engineering: A, 2010The microstructure and mechanical properties of extruded Mg–Sn alloys with 6–10%Sn were investigated. Tensile and compressive strengths increased and yield asymmetry reduced with Sn addition. These changes are attributed to grain refinement and fine Mg2Sn precipitates. However, Mg–10%Sn alloy showed relatively poor tensile ductility due to the presence

2019 hatte allein Polypropylen (PP) einen Anteil von 19.4 % am europäischen Markt und gehört zu den führenden Kunststoffsorten die in den verschiedenen Bereichen eingesetzt werden. Jedoch wird es vorwiegend in Produkten eingesetzt, welche als Wegwerf-Konsumgüter gelten oder nach dem einmaligen Gebrauch entsorgt werden.

Force plane diagrams for slip line fields of indirect type for end-extrusion
International Journal of Mechanical Sciences, 1989Abstract The paper presents some force plane diagrams for slip line fields for end-extrusion through square dies with slipping friction on die and container faces. These diagrams are constructed using a computational procedure based on a nonlinear optimization technique.

In this paper, both direct and indirect extrusions are simulated using a viscoplastic constitutive model. The simulated velocity fields for both direct and indirect extrusions are discussed and compared with experimental results. Advanced numerical techniques are used to trace backward and forward discrete particles of the billet.

In situ characterization of mechanics of deformation including dynamic strain, strain-rate and rotation of material elements was performed in prototypical small length-scale forming operation- indirect extrusion (IE) of commercially pure Lead (Pb) and Aluminum (Al 1100) using Digital Image Correlation (DIC) technique. Effects of scaling and deformation

Study of Temperature Evolution and Metal Flow of 6005A Aluminum Alloy during Indirect Extrusion
Applied Mechanics and Materials, 2011A numerical model has been build up to study temperature evolution and metal flow for the indirect extrusion of 6005A aluminium alloy. Model validation was carried out by comparison between experiments and simulations. Results show a good agreement with each other. The influence of the extrusion parameters on the profile temperature and metal flow were

Comparison of metal flow in un-lubricated direct and indirect extrusion of aluminium alloys
International Journal of Material Forming, 2010The main differences between metal flow in indirect and direct extrusion are described on basis of information achieved from modern FE-simulation coupled with experiments using internal grid patterns inside the metal. It is shown that deformation inside the extrusion is indeed different in the two cases.
