Microstructural stability of Mg-alloys prepared by severe plastic deformation
Piňos, Jakub ; Man, Ondřej (referee) ; Pantělejev, Libor (advisor)
SPD methods allow to obtain ultra-fine-grained structure (UFG) in larger volumes of material and thereby improve its mechanical properties. The microstructure obtained by these methods is thermally unstable, so use of UFG materials at elevated temperatures is limited. Heat exposure leads to grain coarsening and the deterioration of mechanical properties. This work is focused on the thermal stability of Mg-alloys of AZ group.
