Abstract
The SEM/electron back scattered diffraction and serial sectioning procedure have been used to study the five parameter description of grain boundaries in a polygonal ferrite microstructure of 9Cr-1Mo steel. A routine has been evolved to correlate the successive images of a selected region and determine the grain boundary plane morphology. The relative misorientation of the crystallites, in terms of misorientation angle-axis (ω,ȓ), the grain boundary inclination angles [azimuth (γ) and polar (β) angles], and the crystallographic description of the two meeting planes have been studied and compared with random distribution. The low-angle boundaries are found to be persistently present in higher amounts after the grain growth induced by extended annealing.
