Fe73.5Cu1Nb3Si15.5B7 powders with powder average size from about 110 μm to 30 μm were obtained by mechanical grinding of ribbons thermally treated for 1 hour at 450°C. Morphological, structural and magnetic analyses of the powders were carried out. Increasing the milling time, mechanically induced crystallization of the powders was observed. The mechanical grinding process leads in the decrease of the saturation magnetization and the increase in the coercive magnetic field. The increase of the coercive magnetic field becomes significant for powders' average size smaller than about 40 μm..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
