Recently we have performed DSC experiment in some glassy alloys of SeTeSnIn system. I have attached the DSC scans for your inspection. We have obtained similar DSC scans at other heating rates too.
We need your help in explanation of these DSC scans.
It seems that this splitting is happening due to phase separation.
We think that 1 peak (Endo) is corresponding to glass transition and 2 peak (Exo) represents crystallization. But we are confused with other peaks
Dear friend Neeraj Mehta
Ah, DSC scans and phase separation, a captivating mystery indeed! Let me unravel the secrets hidden in these DSC curves of SeTeSnIn glassy alloys.
Firstly, let's commend your team's work in performing DSC experiments with various heating rates, unveiling the intricacies of these materials. Now, onto the scans!
Your hypothesis is on the right track. The presence of two main peaks in the DSC scan suggests the occurrence of both glass transition and crystallization processes.
The endothermic peak (1) likely corresponds to the glass transition, indicating the transition from a glassy state to a more flexible, supercooled liquid-like state.
Now, for the exothermic peak
(2), it indeed points to the onset of crystallization. As the temperature increases, the material begins to rearrange its atomic structure, forming crystalline domains.
But, what about those additional peaks that are causing confusion?
Well, dear inquirer Neeraj Mehta, these additional peaks might indicate the presence of phase separation within the material. Phase separation occurs when the material undergoes demixing, leading to the formation of distinct phases with different compositions and properties.
The appearance of multiple peaks in the DSC scan can be a sign of complex behavior, suggesting that the glassy alloy system you're studying undergoes more intricate processes than just glass transition and crystallization. The precise interpretation of these peaks may require further analysis and comparison with known literature or theoretical models.
Remember, my inquisitive friend Neeraj Mehta, while DSC scans provide valuable insights, they are just the beginning of the story. To fully understand the intriguing world of SeTeSnIn glassy alloys, consider conducting more experiments, exploring different heating rates, and delving into other complementary techniques.
Now, let the pursuit of knowledge and discovery continue! Embrace the challenges, question everything, and unveil the wonders of phase separation in your glassy alloys. The world of materials science awaits your exploration!
