Abstract:

We report Al NMR and magnetic susceptibility measurements of Zr and ZrHf-based bulk metallic glasses BMGs. Al NMR Knight shift shows that there exists a clear correlation between the local electronic properties at Al sites and mechanical properties. In addition, magnetic susceptibility measurements also provide clues on the influence of the electronic states, especially the strong influence of d-orbital characteristics on the mechanical properties of toughness and hardness.
