Study of glass transition of metallic glasses by temperature-modulated differential scanning calorimetry (MDSC)

The glass transition behavior of several Zr- and Mg-based metallic glasses has been studied by temperature-modulated differential scanning calorimetry (MDSC). It is clearly demonstrated that the glass transition can be separa ted from crystallization for these glasses by MDSC. Some glass transitions that could not be observed by a conventional differential scanning calorime try (DSC) have been detected. Furthermore, the complex change of the heat c apacity of the samples during the glass transition and crystallization can now be determined for the first time in one single run.
