摘要

The linear expansion of Zr48Nb8Cu14Ni12Be18 bulk metallic glass (BMG) with excellent glass forming abilityand high thermal stability is investigated by a dilatometry method. The average expansion coefficient is αTG＝1.04×10 -5 K-1 (300-656 K) for the BMG and αTC＝ 1.11×10 -5 K-1 (356～890 K) for the crystallized alloy.The Mie potential as well as the equation of state of the BMG and its corresponding crystallized state are determined from the thermal expansion and ultrasonic data, and the differences among them are phenomenologicallyexplained.
