Mössbauer spectroscopic study of the effect of annealing on the hyperfine field distributions in Fe78B13Si9 metallic glass

Abstract

A study of the effect of annealing temperatures and time periods on the hyperfine field distributions of Fe78B13Si9 metallic glass near and below the crystallization temperatures was made by using 57Fe Mössbauer spectroscopy. The effect of crystallization during annealing as a function of annealing time on the average hyperfine field (<H>) and the relative change of the probability of hyperfine fields, P(H), with respect to that of as-received samples has also been discussed.
