Abstract

The glass transition temperature Tg of eutectic splat-quenched TeGe alloy was measured on a Perkin-Elmer DSC-2 unit over a wide range of scanning rates β from 1.25 to 80 deg/min. The results are described by a linear plot. Tg = A + B lg β with parameters A = 386 K and B = 14.88 over the whole experimental range of β. The physical meaning of the Tg values measured for glassy splats by DSC is discussed. The possibility of using the slope B of the Tg (lgβ) plot for comparison of glasses obtained in different ways is suggested.
