Abstract
The linear expansion of Zr48Nb8Cu14Ni12Be18 bulkmetallic glass (BMG) with excellent glass forming ability and high thermalstability is investigated by a dilatometry method. The average expansioncoefficient 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 asthe equation of state of the BMG and its corresponding crystallized stateare determined from the thermal expansion and ultrasonic data, and thedifferences among them are phenomenologically explained.
