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 … WebGetting Real: The TTT Diagram. Here is the "official" isothermal TTT diagram for eutectoid carbon steel. It is not all that different from the unofficial TTT diagram for the pure iron above, except that the γ → α transformation temperature is now at 723 oC (1333 o F). Look up the phase diagram if you wonder about this.
WebCompare TTT diagrams for hypoeutectoid, eutectoid and the hypereutectoid steels in Fig. 3.6. The incubation period is maximum (critical cooling rate is slowest) in eutectoid steel. M s temperatures are uniformly decreasing in the whole range of carbon. Bainitic part is uniformly shifted to the right. (b) Effect of Alloying Elements:
