Metallography is the study of the physical structure and components of metals, by using microscopy. Ceramic and polymeric materials may also be prepared using metallographic techniques, hence the terms ceramography, plastography and, collectively, materialography.
Metallography – an Introduction | Science Lab | Leica ...
Metallography is the study of the microstructure of all types of metallic alloys. It can be more precisely defined as the scientific discipline of observing and determining the chemical and atomic structure and spatial distribution of the grains, constituents, inclusions or phases in metallic alloys.
Why is metallography important in the manufacturing process?
Old but vital. Thus, metallography is used in almost all stages during the lifetime of a component: from the initial materials development to inspection, production, manufacturing process control, and even failure analysis if needed. The principles of metallography help to ensure product reliability.
What kind of illumination is used in metallography?
Light microscopy has been used for many decades to provide insight into the microstructure of materials. Brightfield (BF) illumination is the most common illumination technique for metallographic analysis.
Many different microscopy techniques are used in metallographic analysis. Prepared specimens should be examined with the unaided eye after etching to detect any visible areas that have responded to the etchant differently from the norm as a guide to where microscopical examination should be employed.
