Abstract: This paper deals with evaluation of hardness fields using Vickers indentation device and a semi-automatic software tool for local hardness distribution mapping. Spec- imens from low carbon pipeline steels were investigated. Dense grids of Vickers imprints were created on the specimens’ surface. Image data of the surface were acquired by a high resolution flatbed scanner with resolution 6400 dpi. The imprints were measured using an custom-developed image processing tool, and from the obtained geometrical characteristics local hardness values were derived. From the local hardness values and their coordinates the hardness field in the whole specimen was interpolated.
