Normalized storage modulus G′ and loss modulus G″ vs temperature in La60Ni15Al25 bulk metallic glass, is the unrelaxed modulus, assumed to be equal to G′ at room temperature. Tα corresponds to peak of main (or α) relaxation and Tβ corresponds to peak of β relaxation.
Normalized loss modulus G″/Gmax as a function of temperature in various bulk metallic glasses (La60Ni15 Al25, Zr55Cu30Ni5Al10 and Cu38Zr46Al8 Ag8). Measurement frequency is 0.3Hz and heating rate is 3 K/min.
Normalized frequency dependence of loss modulus G″/Gmax in various typical bulk metallic glasses: La60Ni15 Al25, La57.5Ni12.5Al17.5Cu12.5, La68.5Ni16 Al14Co1.5, and Zr55Cu30Ni5Al10.
Cole-Cole (CC) plots, loss modulus G″ vs storage modulus G′, in La60 Ni15Al25, Zr55Cu30Ni5Al10, and Cu38Zr46 Al8Ag8 bulk metallic glasses. Measurement frequency is 0.3 Hz and heating rate is 3 K/min.
Temperature dependent peak frequencies of loss modulus in La60Ni15 Al25 bulk metallic glass. The activation energy of the β relaxation can be calculated using an Arrhenius law.
