摘要：

The glass transition temperature of several metallic glasses, La55Al25Ni10Cu10, Nd60Fe30Al10, Y60Fe30Al10, Pr60Fe30Al10, and Sm60Fe30Al10, has been studied by temperature-modulated differential scanning calorimetry (TMDSC). We demonstrate that the glass transition can be separated from crystallization by TMDSC. Glass transition has been observed for Nd60Fe30Al10, Y60Fe30Al10, Pr60Fe30Al10 and Sm60Fe30Al10 ribbons, which occurred at temperatures at least 130 K less than the crystallization temperature in Nd60Fe30Al10, Y60Fe30Al10, Pr60Fe30Al10 and Sm60Fe30Al10 glasses.
