Lab testing equipment

For the common man, the word metallography almost seems alien. It is something, about which, not much is known the world, except for those, who work in that particular industry. For the benefit of those, let us look at what metallography means, the process of metallography and, what the various metallography equipments are.
Metallography is the study of the structure of metals and alloys by various methods, especially optical and electron microscopy. As a process, metallography serves both research and industrial needs. It has been an invaluable tool for the advancement of science and industry for over one hundred years. Metallography is used to reveal the microstructure of metals, which is affected by alloy composition and processing conditions; including cold working, heat treatment and welding. The standard method that is used to determine the constitution of the metallic system is through optical microscopy. They are used in the industry, in order to get some control over the production processes and are also used in the examination of nonmetallic materials.
The process of metallography is very simple and the most important aspect of it, is preparing the metallographic sample. Firstly, the metal surfaces and fractures are examined with the unaided eye or using a vast number of metallography equipments, in order to determine the crystalline, chemical, and mechanical heterogeneity of the article in question. Then there is the process of metallographic etching. It is the process of revealing micro structural details that would otherwise not be evident on the as-polished sample. Polarized light is useful to reveal grain structure, detect preferred orientation, examine oxide surface films, and identify phases of different composition.
Alternatively, X-ray diffraction techniques involve the impingement of a beam of X-rays on the metal specimen and the subsequent diffraction of the beam from regularly spaced planes of atoms; usually, the diffracted rays are recorded on photographic film. The aforementioned technique is used to study the grouping of atoms, amongst other things. By measuring the lines or spots on the diffraction pattern and analyzing the intensity of the deflected rays, information regarding the positioning of the atoms and thereby the crystallography of the phases, the presence of internal strains, and the presence of solute atoms in solid solutions can be obtained.
All these processes that are mentioned above require use of a wide range of metallography equipments; starting from Metallurgical Microscopes, Abrasive Specimen Cutoff Machine, and Polishing Machine to Specimen Mounting Press, Specimen Leveler, Immersion Pyrometer and a whole host of other metallography equipments.  These equipments are usually not that easily available and in most cases require a lot of research into finding the perfect company, for the job.
