As Per TTT diagram, the time interval between Y-axis of temperature to the nose of curve is Incubation period of TTT diagram. Incubation period increases with inncreasing Carbon content but upto 0.8% but the it decreses(In Fe-Fe3C Phase diagram. the curve(A3) between Austenite and Aust-Ferrite transformation at 727 degree decreases means stability of Aust. will increase but then after with increasing carbon the curve(Acm) rises up so Aust. Solubility decreases.). Austenitic Stabilizers increase Incubation period.
