Structural transformations of Fe-based metallic glasses after thermal treatment and the effect of these changes on their thermal stability

The wide-ranging applications of amorphous materials are highly dependent on their thermal stability. In this study, variations in activation energy during different thermal treatment regimes of Fe92Si6C2 amorphous ribbons were investigated using the DSC analysis method. The results revealed that the amorphous phase of the material transitions into various crystalline phases through a sequential formation process. Calculations based on the Ozawa method determined the activation energy to be 143 kJ/mol. This value confirms the material’s high thermal stability and its suitability for operation within the temperature range of 0–100◦C. The findings of this study provide both scientific and practical insights into understanding the behavior of amorphous materials in thermal processes and optimizing their industrial applications.
