摘要：
Influences of casting temperature on the thermal stability of Zr-based metallic glasses (MGs) were analyzed based on continuous heating transformation (CHT) diagrams built up by Kissinger analysis. The results indicate that increasing the casting temperature can enhance the thermal stability of MGs, which attributed to the dissipation of pre-existing metastable local-ordering clusters in the melt resulted from the elevating casting temperature.
