Positron annihilation study of effect of aluminum on iron-based amorphous alloys

Positron annihilation study of effect of aluminum on iron-based amorphous alloys 1 first-author 1 1 1 Testing Center, Shanghai Iron and Steel Research Institute, Shanghai 200940 Testing Center, Shanghai Iron and Steel Research Institute, Shanghai 200940 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.
