Description

Metallic glasses Fe40Ni40P14B6 and Fe40Ni38Mo4B18 were irradiated with 100 keV hydrogen ions at room temperature. Irradiated specimens were examined for surface blistering and gas bubbles using scanning and transmission electron microscopy, respectively. The critical dose for blister formation in metallic glasses is determined to be 1.5x1019 ions/cm2. A comparative study of the alloy Fe40Ni40P14B6 in amorphous and thermally crystallized states showed that the critical dose for blistering in the amorphous state is nearly three times higher relative to that in the crystallized state. TEM investigations revealed the precipitation of implanted hydrogen into gas bubbles in metallic glasses as well as the crystallized alloy. (orig.)
