Metallography is the description of the microstructure of metallic materials. Microscopy is limited to metallographic examinations that are not visible to the human eye, such as microstructural examinations with grain size determination. Macroscopy, on the other hand, includes examinations that are visible to the naked eye, such as the layer structure of a weld seam.
