What is the Ductile-to-Brittle Transition Temperature?

Two broken Charpy impact specimens side by side: a brittle fracture with a flat, granular surface (left) and a ductile fracture with a deformed, necked surface (right).

Have you ever wondered why certain metals behave differently in the cold compared to room temperature? At specific temperatures, the mechanical properties of some materials can change significantly, turning a tough material into a brittle one. This phenomenon is known as the ductile-to-brittle transition. This article explains the mechanism behind it and how it differs […]
