TED-ED: What is metallic glass? - Ashwini Bharathula

The video explores the properties of steel and plastic, highlighting their strengths and weaknesses. It introduces metallic glass, a material combining the best of both worlds, being strong like steel and shapeable like plastic. Metallic glass has unique properties due to its amorphous atomic structure, which lacks the grain boundaries found in crystalline metals. The video discusses the history of metallic glass, its production challenges, and the development of bulk metallic glasses (BMGs). Despite their potential, BMGs face challenges such as high costs and brittleness, but advancements could make them more viable for various applications.

How do the properties of metallic glass change with temperature, and what implications does this have for its use?

What challenges currently prevent the widespread use of bulk metallic glasses in construction?
