| Abstract: | High entropy bulk metallic glasses show promising mechanical and physical properties.Dynamic mechani-cal properties of Ti1 6.7 Zr1 6.7 Hf1 6.7 Cu1 6.7 Ni1 6.7 Be1 6.7 high entropy bulk metallic glass were investigated by mechanical spectroscopy (or called dynamic mechanical analysis).The main (α)relaxation was observed in the framework of the loss modulus G″,which is related to the dynamic glass transition behaviour for the glassy materials.From physical model point of view,dynamic mechanical properties of the Ti1 6.7 Zr1 6.7 Hf1 6.7 Cu1 6.7 Ni1 6.7 Be1 6.7 high entropy bulk me-tallic glass show good agreement compared with the quasi-point defects theory. |
