English summary on page 66 as follows: Metallography is a method of studying the internal structure of metal. Basing himself on the common principle that metal deformation happened not only during metal working but also in the process of usage, the author states that it is necessary to make clear the function of the artifacts before the metallographic analysis on optical microscope with the power of magnification 90-100 X. Metallography makes it possible to define the technology manufacturing metal products. The former of their structures depend on the technology of manufacture.
