Time-Temperature-Transformation Diagram

Time-Temperature-Transformation Diagram

A Time-Temperature-Transformation (TTT) diagram describes the decomposition of the austenite (after prior heating) and the structure generated by this. In order to set up a TTT diagram for continuous cooling rod-shaped test pieces are heated to austenitising temperature in a dilatometer. They are kept at this temperature for a certain time and are then cooled [...]
