用激光闪光法测量了Zr(55) a (10)Ni(5)Cu(30) （at.%）块状金属玻璃中非晶固体和过冷液体的热扩散率。非晶固体的热扩散率和电导率与温度的关系较弱，具有较小的正温度系数。过冷液体的热扩散系数随温度的升高而保持恒定。©2005 Acta Materialia Inc。Elsevier Ltd.出版。版权所有。
We measured the thermal diffusivity of amorphous solid and supercooled liquid in a Zr(55)A(10)Ni(5)Cu(30) (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. © 2005 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
