Mechanical behavior of bulk (ZrHf)TiCuNiAl amorphous alloys

Experimental investigation of thermodynamic behavior and mechanical properties of bulk Zr/Hf-based amorphous alloys revealed that crystallization and glass transition temperatures, hardness and modulus increased with increasing Hf content. It is postulated that the observed strengthening might result from the microstructural changes with addition of Hf in place of Zr
