Characterization of fatigue-induced free volume changes in bulk metallic glass using positron annihilation spectroscopy

Vallery, R. S.; Liu, M.; Gidley, D. W.; Launey, M. E.; Kruzic, J. J. (American Institute of Physics, 2007-12-26)

Depth-profiled Doppler broadening spectroscopy of positron annihilation on the cyclic fatigue-induced fracture surfaces of three amorphous Zr₄₄Ti₁₁Ni₁₀Cu₁₀Be₂₅ metallic glass specimens reveals the presence of a 30–50 nm ...
Quantification of free volume differences in a Zr₄₄Ti₁₁Ni₁₀Cu₁₀Be₂₅ bulk amorphous alloy

Launey, M. E.; Kruzic, J. J.; Li, C.; Busch, R. (American Institute of Physics, 2007-08-01)

Deformation of metallic glasses requires the existence of free volume to allow atomic movement under mechanical loading. Accordingly, quantification of the free volume state of the alloy is crucial to understand it's mec ...
