A shear punch test technique was used for characterization of the mechanical properties of Zr-5Ti-17.9Cu-14.6Ni-10Al bulk metallic glass. The ultimate shear stress values matched very closely with values derived from uniaxial compression tests reported in the literature. This is consistent with a lack of pressure sensitivity in compression reported for this particular metallic glass. Deformation response was strain rate insensitive up to a critical rate, beyond which softening occurred. The latter was attributed to thermal heating effects. (c) 2006 Elsevier Ltd.
