TTT Diagrams and Heat Treatment of Steel | Metallurgy
In large number of commercial heat treatment, the transformations occur during continuous cooling of the steel, and the information from TTT diagrams is not directly useful to these heat treatments. However, TTT diagrams are the basis of certain heat treatments in which transformations occur isothermally, such as: 1. Martempering: It is a hardening process with an objective to minimise distortion [...]
