"The project is aimed to a broadening of physical based knowledge of elevated temperature deformation mechanisms in selected advanced aluminium and magnesium alloys and composites on their bases. Fibre composites as well as particles strengthened composites prepared by modern techniques of powder metallurgy will be used for the investigations. Complex physical and thermodynamical analyses of the behaviour at various deformation modes, i.e., in tensile and compressive creep tests, creep tests at constant structure, tensile and compressive stress-strain tests, relaxation tests, internal friction tests and acoustic tests with simultaneous investigations of structure and its influence on the internal stress in these types of testing should yield new knowledge concerning decisive mechanisms determining this behaviour under various conditions."@en . .
