摘要 Seven Fe-based amorphous alloys have been studied by Doppler broadening and lifetime techniques of the positron annihilation. It is shown that the parameters of positron annihilation in the Fe-based amorphous alloys containing more aluminum are larger than those in the alloys with less aluminum, which means that the existence of element Al in Fe-based amorphous alloys results in more vacancy-like defects.
