Material Engineering Technology Ttt And Cct Curves For Steel Youtube Material engineering technology: ttt (time temperature transformation) and cct (continues cooling transformation) curves. This lecture discusses the ttt and cct curves and different type of phases in steel.
Material Science Ttt Diagram Youtube In this video, you will learn about the ttt plots and how they are formed.📺 subscribe to my channel here: c profdrvasimashaikh?sub c. The construction of cct curves involves conducting experiments where samples of the material are heated to a specific temperature and then cooled at different rates. the resulting phases and microstructures are analyzed, and the data is plotted on the cct curve. this process is repeated for various temperatures to obtain a comprehensive diagram. There are two main types of transformation diagram that are helpful in selecting the optimum steel and processing route to achieve a given set of properties. these are time temperature transformation (ttt) and continuous cooling transformation (cct) diagrams. cct diagrams are generally more appropriate for engineering applications as components. Cooling curves are shown on the temperature log time plot. at the end of the cooling curve phases are shown at room temperature. variation in hardness with distance from jominy end is also shown in the diagram. for cooling curve b, at t 1 temperature minimum t 1 timing is required to nucleate pearlite as per ttt diagram in fig. 8. but material.

Ttt diagram relates the transformation of austenite to time and temperature conditions. hence, the ttt diagram indicates transformation products as per temperature and also the time needed for complete transformation. in fig 1, curve 1 is transformation begin curve while curve 2 is the transformation end curve. New continuous cooling transformation (cct) equations have been optimized to calculate the start temperatures and critical cooling rates of phase formations during austenite decomposition in low alloyed steels. experimental cct data from the literature were used for applying the recently developed method of calculating the grain boundary soluble compositions of the steels for optimization.
