Hypoeutectoid ttt diagram

WebThe TTT diagrams indicate the amount of time required for 1%, 50%, and 100% of the eutectoid reaction to complete at each temperature below the eutectoid temperature. (a) Identify the eutectoid composition and temperature for the Fe-FeC phase diagram. (b) Upon cooling from 1700 °C, identify the reaction that occurs at the eutectoid point. English: TTT diagram of the isothermal transformations of a hypoeutectoid carbon steel, together with its relationship with the Fe-C phase diagram of carbon steels.

WebTTT diagram is also called the Isothermal Transformation Diagram. 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 for an isothermal (constant thermal) heat treatment of a previously austenitized alloy. What is eutectoid alloy? WebThe diagram is nevertheless useful since the transformation behaviour of austenite does not change dramatically unless the steel has a large concentration of solutes. Figure 1: Crystal structures of austenite, ferrite …

WebTTT diagram gives 1- Nature and type of transformation . 2- Rate of transformation. 3- Stability of phases under isothermal transformation conditions. 4- Temperature or time required to start or finish transformation . 5- Qualitative information about size scale of product . 6- Hardness of transformed products. Factors affecting TTT diagram WebStudies of proeutectoid phase transformations generally involve heat treatment in three steps: (1) austenitization (e.g., holding at 1100–1200°C), (2) isothermal transformation in …

WebFigure 1.6 shows the time-temperature-transformation (TTT) phase diagram of eutectoid carbon steel. If cooling from above 720°C is rapid (e.g., less than 5 s), the material does not have enough time to go through equilibrium phase transformation.
