Abstract Internal friction and modulus (especially the changes of it at the temperatures below 500K) for Fe-Ni base metallic glass have been studied during structural relaxation using a Bordoni-type system. The results show that the structural relaxation may consist of two steps: the low temperature (below 500K)structural relaxation governed by TSRO and the high temperature (above 500K) one governed by both CSRO and TSRO. The activation energy of low temperature structural relaxation is about 17 kJ/mol.
