Metallography relates to the methods of studying structure of metals and alloys:

Macro- (Macrography, Macrostructure) Examination is a method of examination of large regions of the specimen surface or fractured section, allowing to determine character of the structure, defects and segregation of alloying elements with the naked eye or under low magnification.

Optical Micro- (Micro-Structure) Examination is a method of studying of micro-structure constituens (grains, phases, non-metallic and intermetallic inclusions, micro-pores, micro-cracks, fructures, etc.), by means of the Metallurgical Microscope.

Scanning Electron Microscope Examination is a method of studying of micro-structure constituens (grains, phases, non-metallic and intermetallic inclusions, micro-pores, micro-cracks, fructures, etc.), by means of the Scanning Electron Microscope.

X-Ray Microanalysis is a method of qualitative and quantitative chemical analysis of small areas (separate structure constituents) of the alloy. X-Ray Microanalysis is usually combined with Scanning Electron Microscope.

Digital photography and image analysis are used for quantitative estimation of different structure constituents.
