  • Characterisation of Cu-Al-Ni melt-spun ribbons after different thermal and mechanical treatments [Elektronski vir]
    Unterweger, Elfride ...
    In order to obtain thin semi-finished products for microactuator applications CuAlNi ribbons were produced via melt-spinning. Initially a series of melt-spinning experiments was performed in order to ... study the interrelationships between processing parameters (wheel velocity, nozzle type and distance) and the geometry of the achieved ribbons. To improve the homogeneity of the thickness of the ribbons a rolling device was used. Microstructure evaluation has been done with optical and scanning electron microscope and X-ray diffraction analysis. One of the significant results is that the grain size for the chosen alloy composition is higher than expected for a rapid solidification technique. The martensite and austenite start and finish temperatures were determined by Differential Scanning Calorimetry. Furthermore some results of the influence of heat and mechanical treatment on microstructure and mechanical as well as functional properties will be presented.
