105. Textures, microstructures and metallography

Metals and related materials provide a great deal of information on the ways in which they were manufactured and used. Some of this information can be gained from a simple visual examination of the objects. Supplementary information can be gained through a consideration of the chemical composition of the material (e.g. metal alloy type, impurities, etc) and some from the examination of the structure of the materials at a microscopic level.
