Education / Definitions

Metallurgists and metallurgical engineers have their own "lingo" (technical or semi-technical terms which have specific meaning within the profession) i.e., dimple rupture,  "rock candy" fracture and cleavage fracture. This section of web pages explains some of the terms used in the metallurgical profession as well as instrumentation used in failure analysis.
