Metallography, Studies on

Metallography is a discipline that studies the internal structure of metals and alloys. It is the forerunner of the formation of physical metallurgy, the foundation of the formation and development of metallurgy, and also an important part of metallurgy. Microscope (optical and electron microscope) and X-ray diffraction are mainly used in metallurgy or physical metallurgy to analyze the microstructure and macrostructure of materials.

Brief History

The term metallography first appeared in The New Oxford Dictionary of Englishin 1721, when it meant the knowledge of metals and their properties, not the organization or structure. Metallographic technology, as a means of microstructure research and observation and analysis of metal materials, began in the early nineteenth century. The rise of metallography began with the study of the microstructure of steel. British microscopist and geologist Henry Clifton Sorby first observed polished and etched steel specimens with an optical microscope...
