摘要：
Crystallization kinetics of Cu47Ti34Zr11Ni8 and Cu47Ti33Zr11Ni8X1 (X = Si,Sn) metallic glasses was investigated by the Johnson-Mehl-Avrami method. The Avrami exponent of 2.5 similar to 3.1 implies that the crystallization is governed by three-dimensional growth with an increasing nucleation rate. Viscosity measurements show that phase separation in amorphous phase and/or nanocrystallization occur near the glass transition region for the Si-containing metallic glass.
