A. Cserei et al., SHORT-RANGE ORDERING AND CRYSTALLIZATION OF LONG-TERM MELTED FE83P17 AMORPHOUS-ALLOYS, Hyperfine interactions, 94(1-4), 1994, pp. 2181-2186
Mossbauer spectroscopy, X-ray diffractometry and DSC measurements were
used to study the as-quenched state and the crystallization of Fe83P1
7 amorphous alloys quenched at several different cooling rates. The me
lt temperatures investigated were 1100 and 1250 degrees C. We have fou
nd changes in the hyperfine field distribution curves as a function of
the quenching rate. These changes can be attributed to relaxation eff
ects which are more considerable than those observed in Ni(Fe)P alloys
. On the other hand, we have found differences in the phase compositio
n of the partially crystallized alloys kept at different melt temperat
ures (but quenched at the same rate) at the same stage of crystallizat
ion. These can be associated with the similar effect of long-term melt
ing as found earlier in Ni(Fe)P and FeB alloys. This effect can also b
e expected theoretically in the investigated temperature range.
