Surface deformations on both amorphous and polycrystalline alloys of METGLASS 2826A caused by high dose bombardment of helium ions of energy 2 and 3.52 MeV were examined by RBS analysis and SEM. Both observations confirm that the resistance of the amorphous form against flaking is 70% higher. The morphology of the metallic glass surface after flaking is characterized by a wave-like structure. For higher energy bombardment and higher current density the surface deformations are characterized by competition of two processes, i.e. exfoliation and flaking presumably due to temperature effects.
