@amazeifystore: Why did these ships just snap in half? 🚢⚓️ In the freezing North Atlantic, tough steel hulls started acting like glass. This is the ductile-to-brittle transition, a hidden threshold that changed engineering history forever. When the temperature dropped, the metal lost its ability to stretch and simply shattered. It is the reason why Charpy impact testing is a standard today. Have you ever seen a material fail in a way you did not expect?
