Internal friction in the bulk metallic glass [Zr.sub.41.2][Ti.sub.13.8][Cu.sub.12.5][Ni.sub.10][Be.sub.22.5] in amorphous and crystalline states

The low-frequency temperature dependences of the internal friction and the Young's modulus of the Vitreloy-1 alloy ([Zr.sub.41.2][Ti.sub.13.8][Cu.sub.12.5][Ni.sub.10][Be.sub.22.5]) have been studied in amorphous and crystalline states. The increase and maxima of the Young's modulus due to...

Description
Summary:The low-frequency temperature dependences of the internal friction and the Young's modulus of the Vitreloy-1 alloy ([Zr.sub.41.2][Ti.sub.13.8][Cu.sub.12.5][Ni.sub.10][Be.sub.22.5]) have been studied in amorphous and crystalline states. The increase and maxima of the Young's modulus due to structural transformations are observed during the crystallization of the Vitreloy-1 alloy from the amorphous phase in the range from the glass transition temperature (325°C) to the temperature of the secondary crystallization (460°C). At 200°C, the internal friction in a partially crystallized Vitreloy-1 alloy exhibits a peak of presumably an interface nature.
