Abstract
Continuous cooling transformation (CCT) diagrams are usually plotted using dilatometer tests on a hot simulator and metallographic analysis. However, for some steel grades it is not sufficient to use conventional methods to plot CCT diagrams. Therefore, how to accurately plot CCT diagrams for such steel grades is an important task in the development of new metals and the determination of processing technology. A new method of using differential scanning calorimetry in addition to the dilatometer test and microstructure examination is proposed to accurately plot the CCT diagrams. An example of a CCT diagram for an alloy steel is also shown.
