Using The Isothermal Transformation Diagram

So here is our isothermal transformation diagram for the eutectoid steel composition. We have plotted along the x axis the time and its in the scale of logarithms and were looking at the temperature on the y axis.

Time Temperature Transformation Ttt Diagram Powerpoint

The higher the temperature the thicker the layers.

Using the isothermal transformation diagram. They are generated from percentage transformation vs time measurements and are useful for understanding the transformations of an alloy steel at elevated temperatures.

Of hardened alloy fe 28 mn 85 al 1 c 125 si. Isothermal transformation diagrams also known as time temperature transformation ttt diagrams are plots of temperature versus time usually on a logarithmic scale. Diagram of phase transformations in the austenite.

The isothermal transformation diagrams are a graph or pictorial representation of the temperature changes with respect to time in the particular alloy composition of the material and it signifies. These are the times asked for in the problem statement. 1019 using the isothermal transformation diagram for an iron carbon alloy of eutectoid composition figure 1022 specify the nature of the final microstructure in terms of microconstituents present and.

Ttt diagram gives 1 nature and type of transformation. The complete isothermal transformation diagram for an iron carbon alloy of eutectoid composition. A from figure 1022 a horizontal line at 550 c intersects the 50 and reaction completion curves at about 25 and 6 seconds respectively.
