Abstract
Zr 60Ti 5Ag 5Cu 12.5Ni 10Al 7.5 glassy powders produced by ball milling of crystalline compounds were consolidated by uniaxial hot pressing. The consolidation parameters were chosen in order to obtain partially crystallized bulk samples with a composite microstructure consisting of glassy, quasicrystalline and tetragonal CuZr 2 phases. Hardness measurements reveal promising mechanical properties: Vickers hardness of 4.61 GPa and estimated yield strength of 1.53 GPa. These values are comparable to those reported for bulk Zr-based glassy alloys prepared by other techniques.
