Description
Amorphous Fe80B20 and Fe40Ni40P14B6 alloys are studied before and after low temperature electron irradiations by positron lifetime and magnetic after-effect methods. The results show that in amorphous state all positrons are trapped by quenched-in voids of less than one atomic volume. Electron irradiation produces vacancy-like defects which recover continuously up to room temperature making only a few reorientation jumps before annealing. (author)
