THE IMPACT OF COMPOSITION DEPENDENT AND PROCESS-RELATED PROPERTIES IN THE LASER CUTTING OF METALLIC GLASSY TAPES
PRODUCTION ENGINEERING ARCHIVES 23(2019), pp. 41-46
A short survey is reported on the advantageous and disadvantageous properties of soft magnetic glassy tapes to build stator and rotor elements for the increase of motor efficiency. The relative high saturation magnetization and the relative permeability of these alloy groups seem to be promising in this applica-tion field. On the other hand, the sample thickness (30 µm) displays limitations in terms of a filling factor. High hardness of tapes hinders the effectivity of mechanical shaping. Laser cutting can be suc-cessful as shaping method, presuming that the extension (thickness) of heat affected zone (HAZ) can be successfully reduced below 50µm, avoiding the brittleness evolution.
