In this study, new non-equiatomic high entropy bulk metallic glass (HEBMG) Zr₃₃Hf₈Ti₆Cu₃₂Ni₁₀Co₅Al₆ was developed according to the Cu₄₇Zr₄₇Al₆ prototype BMG. Kinetic studies were performed with non-isothermal DSC for the BMG and the HEBMG, and their thermal properties were compared. Calculation of activation energies by different methods indicated that E_g is higher for the HEBMG than the BMG, while E_p is lower for the HEBMG than the BMG, and E_x is similar for both alloys. The values of structural relaxation enthalpy for the BMG and the HEBMG were 4.95 J/g and 8.19 J/g, respectively. Free volume was calculated at room temperature and T_g. By doing so, the direct correlation between fragility, structural relaxation enthalpy, diffusion, and free volume was shown. Using a compression test at room temperature, a 58% improvement in plastic strain was obtained for HEBMG, which confirmed the …
