Measurements of several physical properties of the Zr54.5Ti7.5Cu20Al10Ni8 alloy in the amorphous and crystalline states

The mass density, Young's moduli, shear moduli, vibration damping, microhardness, resistivity, enthalpy of crystallization, Poisson ratio, and metallography of Zr54.5Ti7.5Cu20Al10Ni8 were studied both in amorphous and crystalline states. The resistivity measurements show the strong influence of crystal structure on electrical conductivity. For the amorphous state, the resistivity is (1.85±0.02)×10-6 Ωm. Crystallization of the alloy reduces the resistivity by 54.1% to (8.50±0.04)×10-7 Ωm. The microhardness of the amorphous alloy is 411±18 VHN, the crystalline material has a microhardness of 629±53 VHN. The damping vs. strain amplitude curve for the specimen in the amorphous state shows no change in damping with increased strain amplitude.
