TTT Diagrams: Introduction and Limitations | Material Engineering As shown in complete TTT diagram for eutectoid steel in figure above approximately 550°C-600°C, austenite transforms completely to pearlite. Below this range up to 450°C, both pearlite and bainite are formed. Finally, between 450°C and 210°C, the reaction product is bainite only. Transformation Diagrams (CCT & TTT) - SIJ Given below is a typical TTT diagram. Time-temperature isothermal transformation (TTT) diagram for AISI type 6150 carbon steel, austenitized at 850°C. Continuous cooling transformation (CCT) diagrams Measure the extent of transformation as a function of time for a continuously decreasing temperature.
