This paper reports the observation of the clear Invar effects of (Fe71.2 B24 Y4.8) 96 Nb4bulk metallic glass. The Invar effects of (Fe71.2 B24 Y4.8) 96 Nb4alloys in different structural states are also investigated in situ through cyclic thermal dilation tests at different cyclic temperatures. The results show that these Invar effects are strengthened in the relaxation amorphous state, weakened in the nanocrystalline state, and absent in the complete crystalline state. X-ray diffraction and Mössbauer spectroscopy demonstrate that the structural influences on Invar effects can be explained by the different local atomic arrangements around Fe atoms in different structural states.
