To investigate changes in the microstructure of selected megnesium and aluminium alloys and their composites after mechanical cycling using light metalography and acoustic methods (acoustic emission and internal friction measurements). 2. To estimate the role of twins in the fatigue process at various temperatures. 3. To reveal the contribution of twins recombination in the selected alloys and composites and the influence of solute atoms on these processes. 4. To examine the mophology of fatigue fractures in the selected alloys and composites using light metalography and electron microscopy. 5. To estimate the influence of load amplitude on the changes in microstructure and fracture mechanism. 6. To estimate the influence of temperature on recovery mechanisms operating in materials after mechanical cycling using internal friction measurements."@en . . .
