It is important to note that there is not a single TTT or CCT diagram like the Iron- Carbon diagram. Different steels have different TTT and CCT diagrams.

Imagine, for example, some pure iron that was kept at a temperature of oC ( .. Here is the "official" isothermal TTT diagram for eutectoid carbon steel.

4 The following phases are involved in the transformation, occurring with iron- carbon alloys: L - Liquid solution of carbon in iron; δ-ferrite – Solid solution of. TTT diagram is a plot of temperature versus the logarithm of time for a steel alloy of The complete isothermal transformation diagram for an iron-carbon alloy.C metastable equilibrium diagram and TTT diagrams for plain carbon hypoeutectoid, eutectoid and hypereutectoid steels M S (a) Fe-Fe 3 C metastable phase diagram (b) TTT diagram for hypoeutectoid steel (c) TTT diagram for eutectoid steel (d) TTT diagram for hypereutectoid steel γ=austenite α=ferrite CP=coarse pearlite M=martensite M S.

This latest version of the Iron Carbon Diagram is multi-dimensional. The crystal and grain structures in steels and cast irons are easier to understand with the use of colorful graphics combined with high and low magnification photo-micrographs of four carbon steel alloys, and two popular types of cast iron.

  1. I can not take part now in discussion - there is no free time. But I will soon necessarily write that I think.

  2. I consider, that you commit an error. I suggest it to discuss. Write to me in PM.

  3. I here am casual, but was specially registered at a forum to participate in discussion of this question.

  4. I think, that you are not right. Let's discuss it. Write to me in PM, we will talk.
