Thermal diffusivity and conductivity of Zr55Al10Ni5Cu30 bulk metallic glass

We measured the thermal diffusivity of amorphous solid and supercooled liquid in a Zr55Al10Ni5Cu30 (at.%) bulk metallic glass using a laser flash method. The thermal diffusivity and conductivity of the amorphous solid were weakly temperature-dependent, with small positive temperature coefficients. The thermal diffusivity of supercooled liquid remains constant with temperature.
