Agnirva Space Premier League - Expedition #30684: Unlocking Metallic Glass: How Sulfur and Space Shape Structure

Metallic glasses are materials that lack a crystalline structure, giving them unique mechanical and magnetic properties. These properties make them ideal for transformer cores, biomedical devices, and precision instruments. However, forming metallic glasses—especially those containing sulfur—is challenging due to their tendency to crystallize upon cooling.

The experiment "Topological Frustration and Glass-forming Ability of Sulfur-containing Metallic Glass-formers" investigates how adding sulfur affects the glass-forming ability of these alloys in microgravity.

In space, researchers can study how atoms arrange themselves during cooling without the influence of gravity-induced convection. This helps isolate the role of atomic structure—known as topological frustration—in preventing or promoting crystallization.

Understanding these dynamics allows scientists to develop new metallic glass materials with better performance and stability. The ISS provides an ideal lab to cool these alloys uniformly, enabling deeper insight into their glass-forming tendencies.

Results from this experiment could guide the design of novel materials with tailored properties for electronics, magnetics, and structural applications.
