Correlation between the fragility of supercooled liquids and thermal expansion in the glassy state for Gd-based glass-forming alloys

Dilatometric measurements were performed to obtain the average thermal expansion coefficients of a series of Gd-based bulk metallic glasses. The fragilities of these alloys were determined based on differential scanning calorimetry measurements. It was found that there is a linear correlation between the fragility parameter of supercooled liquids and the average thermal expansion coefficient in Gd-based bulk metallic glass-forming alloys.
