Structural and Mechanical Characterization of ZrTiCuNiAl Bulk Metallic Glass.

Thermal stability, structure and mechanical properties of the multi-component ZrTiCuNiAl bulk metallic glass have been studied in detail. The glassy material displays good thermal stability against crystallization and a fairly large supercooled liquid region of 52 K. During heating, the alloy transforms into a metastable icosahedral quasicrystalline phase in the first stage of crystallization.
