Abstract

Abstract : One of the simplest, most popular, and productive ways to conduct research and testing in the field of materials science is through the use of metallographic study. Technological boon in the field of metallographic study, opens new gateway for materials characterization through image processing technologies. Image segmentation, edge detection, and roughly estimating grain size are the three main goals of metallographic image processing. The objective of this paper was to determine the grain size of EN9 steel by applying different clustering techniques to the image textured data, collected from EN9 steel metallographic specimens in normalized and annealed condition. In order to determine the average grain size in EN9 steel specimens when seen with a metallurgical microscope, this article blends the ideas of image processing with various hierarchical clustering methodologies to study material characteristics.
