Crystallization behavior and consolidation of ball milled Zr60Ti5Ag5Cu12.5Ni10Al7.5 glassy powders

Zr60Ti5Ag5Cu12.5Ni10Al7.5 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 CuZr2 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.
