Abstract

Mössbauer spectroscopy, X-ray diffractometry and DSC measurements were used to study the as-quenched state and the crystallization of Fe83P17 amorphous alloys quenched at several different cooling rates. The melt temperatures investigated were 1100 and 1250 °C. We have found changes in the hyperfine field distribution curves as a function of the quenching rate. These changes can be attributed to relaxation effects which are more considerable than those observed in Ni(Fe)P alloys. On the other hand, we have found differences in the phase composition of the partially crystallized alloys kept at different melt temperatures (but quenched at the same rate) at the same stage of crystallization. These can be associated with the similar effect of long-term melting as found earlier in Ni(Fe)P and FeB alloys. This effect can also be expected theoretically in the investigated temperature range.
