Original abstract

Mechanical properties of an aluminium thin film were measured by microcompression and indentation tests. The microcompression technique combines preparation of specimens using focused ion beam (FIB) and compression test by a nanoindeter device. Cylindrical specimens were prepared by focused ion beam milling. The height of cylindrical specimens was about 2 mm and their diameter about 1,3 mm. The load and displacement were continuously measured during tests. The stress-strain curves were obtained in two representations. Stresses of the first plastic bursts were determined in both representations. Hardness and Young modulus were measured by indentation test using continuous stiffness method. Representative values of thin film were calculated.

Mechanické vlastnosti tenké hliníkové vrstvy byly měřeny mikrokompresí a indentací. Mikrokomprese kombinuje přípravu vzorků pomocí fokusovaného iontového svazku a kompresní text pomocí nanoindentoru. Válcové vzokry o průměru 1.3 mikrometru a výšce 2 mikrometrů byly připraveny pomocí fokusovaného iontového svazku. Během testu byly zaznamenávány síla a posunutí indentoru. Křivky napětí-deformace byly získány ve dvou reprezentacích. Tvrdost a modul pružnosti byly měřeny metodou "continuous stiffness measurement".
