It is widely accepted that the structures and properties of solids are influenced greatly by its matrilineal liquid state. In the present paper, the correlation between the internal friction behavior of Zr 55 Al 10 Ni 5 Cu 30 BMG samples and their quenching temperatures was investigated. The measured tan ϕ − T curves showed that the positions of internal friction peaks did not change with frequencies for all samples. But they were shifted to higher temperature with the quenching temperature elevated. In the supercooled liquid, the higher the melt temperature was, the lower the internal friction was. Based on the theory of Perez, the correlation parameter χ was deduced from tan ϕ − f curves in the vicinity of T g . The change of the value of χ showed that the melt temperature had significantly influence on the mechanical relaxation of metallic glasses.
