| Abstract: | The shear school holds the view that there exists Spinodal like decomposition of solute atom during incubation and early stage of Bainitic transformation. We carried out experiments to verify it. Table 1 gives four alloys with different structures used in the experiment, and the corresponding heat treatment techniques. Figs.1 through 4 give the transmission electron microscopy (TEM) patterns of the four alloys. They show that there are four satellite spots around each main diffraction spot. The X ray diffraction (XRD) profile (Fig.5) shows that there are two sidebands beside 200 main diffraction peak. Our experimental results support the shear school. |
