Reversible structural relaxation has been studied in (Fe1−xNix)80B10Si10 by differential scanning calorimetry and x-ray diffraction. It is found that surface crystallization plays a major role in inhibiting reversibility. In consequence, previously published data have presented a misleading picture about the composition dependence of the reversible effect in Fe-Ni-B-Si, which simply increases monotonically with Ni composition. There is no evidence that chemical short-range order plays any role in reversibility, and the data have been quantitatively modeled by simply assuming that reversible relaxation is caused by the thermal repopulation of excited structural states.
