The structural relaxation in a Zr 55 Cu 30 Ni 5 Al 10 bulk metallic glass was investigated by volume and enthalpy relaxation at various temperatures. The relaxation kinetics was well described by a stretched exponential relaxation function, UΓ°tΓ ΒΌ expΒ½ΓΓ°t=sΓ b . The Kohlrausch index, b, ranged from

## Abstract The electrochemical behaviour of the Zr~55~Cu~30~Al~10~Ni~5~ amorphous alloy prepared as cylindrical bulk samples with 7 mm diameter has been investigated. Cyclic potentiodynamic polarization measurements carried out on the cross section areas of the samples in airβsaturated and nitroge
The strain rate effects on the deformation behavior of bulk-metallic glasses (BMGs) are investigated. The loading-unloading-reloading tests were performed with the same strain rates for the loading and reloading. The deformation for both (Zr 55 Al 10 Ni 5 Cu 30 ) 99 Y 1 and Cu 45 Zr 47.5 Ag 7.5 BMGs
