Deformation Behaviour of Advenced Magnesium and Aluminium Alloys
Jäger, Aleš
Aluminum and magnesium alloys are often considered as promising materials due to high strength/density ratio. In general, light alloys are very attractive structural materials for applications where environmental protection or weight reduction play essential role. Therefore, it is of interest to investigate microstrucrure and its changes during plastic deformation because it helps to understand the nature of solute effect and processes taking place during plastic deformation. The aim of this work is to reveal microstructures, deformation characteristics and micromechanisms of plastic deformation at different strain rates and temperatures in selected light alloys. Two commercially available alloys were used in this work: AZ31 rolled magnesium alloy and AA6082 extruded aluminium alloy. These alloys were studied with the help of various experimental techniques such as tensile testing, light microscopy, electron backscatter diffraction (EBSD) and X-ray diffraction. Abstrakt Hlinikove a horcikove slitiny jsou povazovany za vysoce perspektivni materialy, protoze nabizeji velmi dobry pomer pevnosti k hustote. Tyto lehke slitiny nalezaji uplatneni pfedevsim v aplikacich, kde je kladen duraz na ochranu zivotniho prostredi a nebo snizeni hmotnosti. Detailni studium jejich mikrostruktury a deformacniho...
