    Metallographic polishing techniques for electron microscopy are subject to stringent requirements as to quality. In order to use the extremely light etches required in electron metallography, it is essential that the surface be polished without relief effects and be free from distortion or flowed metal. The factors that must be considered in metallographic polishing are discussed, and the techniques that can be used to attain satisfactory polish are presented. A summary of the mechanical polishing methods used by members of Subcommittee XI, ASTM Committee E-4, on Electron Microstructure of Steel is also included.
