Title: Crystallization and thermophysical properties of Cu{sub 46}Zr{sub 47}Al{sub 6}Co{sub 1} bulk metallic glass

Phase evolution of two-step crystallization and the subsequent B2-phase transformation was presented in Cu{sub 46}Zr{sub 47}Al{sub 6}Co{sub 1} bulk metallic glass (BMG) during heating process. Thermophysical properties, i.e. the thermal diffusivity and the specific heat capacity, of the BMG in amorphous solid state and supercooled liquid state as well as its crystalline counterparts were measured from room temperature to 1070 K. The thermal conductivity was also calculated through combination of the data of the thermal diffusivity and the specific heat capacity. The possible influence of the crystallization on the thermophysical properties was discussed.
