The glass transition behaviour of the four metallic glasses La55Al25Ni20, Zn65Mg35, and Nd60Fe30Al10 and Zr30Y30Al15Ni25 has been studied by temperature-modulated differential scanning calorimetry (MDSC). It is clearly demonstrated that the glass transition can be separated from crystallization by MDSC. Two glass transitions have been observed for Zn65Mg35, Nd60Fe30Al10 and Zr30Y30Al15Ni25. Owing to the clearer observation of the glass transition, calculation of the reduced glass temperatures T-rg (glass transition temperature divided by the melting point) can now be made with greater confidence.
