摘要
The low-frequency temperature dependences of the internal friction and the Young’s modulus of the Vitreloy-1 alloy (Zr41.2Ti13.8Cu12.5Ni10Be22.5) 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.
