Homology Applied to Characterization of Welded Grain Structures in Low Carbon Steel

Abstract:

In the present work, organization of grains within the weld zone in SS400 low carbon steel is investigated. A classification method based on the concept of topological quantity is proposed to investigate the heat affected zone (HAZ) and the center of the weld metal zone (WMZ). The image of each area includes various grains. By using the conventional image analysis techniques, we can analyze the distribution of its size. However, it is difficult to capture the structure of each. In addition, analyzing each grain does not mean the elucidation of the whole. By calculating the average amount of homology of the grains, we make a distinction in these areas quantitatively.
