The Time-Temperature-Transformation Curve - Gear The effect of alloying on the shape of the TTT diagram is shown in Figure 8. Figure 7: Comparison of the effect of carbon on the TTT curves of plain carbon steel. Left is SAE 1020 steel. Right is SAE 1080 steel. Carbon pushes the nose (or knee) of the TTT curve to the right, retarding kinetics [3]. Time Temperature Transformation (TTT) of Austenite ... TTT diagrams of plain carbon steels (Fig. 3.6) and some alloy steels have single knee. Actually, single knee curve is a particular case where super-imposition of temperature intervals for pearlitic and bainitic transformations takes place. (a) Bainitic transformation is complete (Fig. 3.5 a). PDF T-t-t Diagram for Eutectoid Steel T-T-T diagram is also called isothermal transformation diagram [Temperature-Time - Transformation]. It is a plot of temperature versus the logarithm of time for a steel alloy of definite composition. It is used to determine when transformations begin and end...
