Asymmetric rolling of EN AW-5454 aluminium alloyKraner, Jakob (Avtor) Fajfar, Peter (Mentor) Palkowski, Heinz (Komentor) asymmetric rollingaluminium alloysmechanical propertiesRolling is as one of the most commonly used metal forming processes. In industrial practice, symmetric rolling technology is usually used. Nevertheless, it is possible to conduct an asymmetric rolling process. Introducing asymmetry in the rolling process is possible via different means. Asymmetry imparts changes in the technical and in the economical aspect of the rolling process. In the framework of this master thesis, the asymmetric rolling of EN AW-5454 aluminium alloy was investigated. For the planned rolling types, numerical simulations with similar conditions and entry rolling parameters were conducted. Symmetric and asymmetric rolling experiments were performed on a laboratory rolling mill and the exit obtained parameters were compared. The deformed workpieces were heat-treated and annealed. Different mechanical tests were performed on both the heat-treated and the deformed samples to find out the influence of asymmetric rolling on the resulting properties. Tensile, plastic strain ratio and hardness tests were performed respectively. Standard sample preparation procedures were applied to the samples subjects. Investigations of light optical and scanning electron metallography were carried out.20182018-09-15 07:46:14Magistrsko delo/naloga103255sl
