dc.description.abstractThe Center for Electromechanics at The University of Texas at Austin has investigated the use of an electromagnetic railgun accelerator for the deposition of non-crystalline metals. The two main objectives of the study were to produce non-crystalline metal deposits in single thin layers (˷ 25lJm thick) and to determine the feasibility of building thicker layers by making multiple deposits. Deposits have been analyzed using a variety of techniques, including electrical resistivity and resistivity ratio, x-ray diffraction, and transmission electron microscopy. Differential scanning calorimetry was carried out at Battelle Columbus Laboratories. The measurements show that CEM-UT -has produced non-crystalline Fe78B13Si9 deposits. Single and multiple-layer non-crystalline deposits with thicknesses of up to 36 µm have been produced, and the upper thickness limit of the technique has not yet been determined.en
