The kinetics of volume relaxation for Pd46Cu 35.5P18.5 and Pt60Ni15P25 BMGs were investigated by high-resolution density experiments at room temperature. The distinct two- steps relaxation behavior was observed for as-quenched BMGs. After pre-annealing as- quenched Pd46Cu 35.5P18.5 BMG in the supercooled liquid region, the relaxation process changed into a single relaxation process well described by a stretched exponential relaxation function. Meanwhile, the pre-annealed Pt 60Ni15P25 BMG still remained a two-steps relaxation behavior. The volume relaxation data of as-quenched Pt 60Ni15P25 BMG was analyzed on the base of the structural inhomogeneity composed of volume compression and expansion regions in the like sites during structural relaxation.
