    Laser nonuniform annealing of amorphous metal sheets, effects on structure and magnetization

    A previos thermal model for the heat treatment of a little metal ribbon, moving under a broad laser beam with Gaussian intensity distribution, is elaborated in order to apply it also in the opposite experiment...

    Partial anisotropy induced by low-field thermomagnetic treatment of noncrystalline ribbons

    The initial development of the transverse anisotropy induced by magnetic annealing is investigated for magnetizing field values which are much smaller than the ones generally employed. Measurements of Young mo...

    Mössbauer spectroscopy effectiveness in investigating the influence of special heat treatments of metallic glasses

    The as quenched amorphous ribbons are in a metastable condition and need a thermal treatment to relax internal stresses and/or to induce magnetic anisotropy. The evaluation of the results of various annealing ...

    Inert-Gas-Assisted Cutting of Low-Carbon Steel Sheets Using a High-Power Laser System

    The high productivity that a laser system could have if employed in an integrated working system has induced the authors to confront the problem of cut surfaces obtained with laser technology. A cut of inferio...
