Fragility plot of the relaxation time at the glass transition onset as a function of inverse temperature for .
Enthalpy recovery measurements in the glass transition region after (a) isothermal relaxation for at three different temperatures; (b) isothermal relaxation from the amorphous state for varying time at . In addition, the measurement for an unrelaxed “as-received” sample is shown.
Representative HRTEM image and diffraction pattern of the sample annealed for at . No evidence of nanocrystals was found and the alloy remained fully amorphous.
Enthalpy and free volume difference vs. temperature for different free volume states of the amorphous alloy. Here the “as-cast” data points at 585, 595, and were determined by adding the measured values of enthalpy recovery after annealing for a time [from Fig. 2(a)] to the enthalpy of the supercooled liquid from Ref. 27. At additional data were collected for intermediate annealing times of , , and [Fig. 2(b)] and those data are also shown here.
