DEMONSTRATION OF DYNAMIC SCALING IN PHASE-SEPARATION OF AMORPHOUS CU12.5NI10ZR41TI14GE22.5

The scaling property of small angle neutron scattering of phase separa tion in supercooled Cu12.5Ni10Zr41Ti14Be22.5 liquid has been studied. By applying several scaling functions, we have presented a detailed dy namic scaling analysis of the events and revealed that although the ph ase separation in this deeply supercooled liquid exhibited abnormal ki netics, the scattering function S(q, t) reached the scaling state even in the very early stage. It has been found that the scaling function F(eta') = q(m)(3)S(q, t), where eta' = q/q(m) and q(m) is the peak pos ition of S(q, t), over-predicts the time needed for achieving the scal ing state, due to the time-dependent invariant.
