Abstract

All three methods of the positron annihilation technique were applied to investigate amorphous metals. Samples of Fe40Ni40Si14B6 and Fe40Ni40P14B6 were prepared by the melt spun technique with constant ejection pressure and orifice size but at varying quenching rate and melt temperature. The influence of the production process leading to different Hc for the samples, the effect of heat treatment, cold rolling, and electron irradiation were studied. The measured dependence of positron annihilation parameters on the above treatments indicates the presence of positron-active trapping centres in the amorphous phase.
