摘要

The glass transition temperature of several metallic glasses, La_(55)Al_(25)Ni_(10)Cu_(10), Nd_(60)Fe_(30)Al_(10), Pr_(60)Fe_(30)Al_(10) and Sm_(60)Fe_(30)Al_(10), 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 Nd_(60)Fe_(30)Al_(10), Y_(60)Fe_(30)Al_(10), Pr_(60)Fe_(30)Al_(10) and Sm_(60)Fe_(30)Al_(10) ribbons, which occurred at temperatures at least 130 K less than the crystallization temperature in Nd_(60)Fe_(30)Al_(10), Y_(60)Fe_(30)Al_(10), Pr_(60)Fe_(30)Al_(10) and Sm_(60)Fe_(30)Al_(10) glasses.
