![]() ![]() Based on the dilatometric tests, hardness, and microstructural investigation, a deformation-CCT diagram was plotted. In addition, critical temperatures were calculated using Thermo-Calc, JMatPro, and empirical formulations. It was tried to predict the phase transformations via a continuous cooling transformation (CCT) diagram calculated by JMatPro using the results of prior austenite grain size measurement. The microstructure evolution was characterized using light microscope (LM), scanning electron microscope (SEM), transmission electron microscope (TEM), x-ray diffraction (XRD), and electron backscatter diffraction (EBSD). ![]() In this work, the microstructural evolution and the phase transformations on a 0.22 wt.% carbon bainitic forging steel are investigated using a deformation dilatometer.
