Metallographic Examination The study of a material’s microstructure. Metallographic examinations are generally performed by using optical microscopes to analyzing micrographs, and provide insight into the past and future performance of base materials, parts, and experimental alloys.

The basic steps for proper metallographic examination include: sampling, specimen preparation (sectioning and cutting, mounting, planar grinding, rough and final polishing, etching), microscopic observation, digital imaging and documentation, and quantitative data extraction through stereological or image analysis methods. Metallography is the study of a materials microstructure. Analysis of a material's metallographic microstructure aids in determining if the material has been processed correctly and is therefore a critical step for determining product reliability and/or for determining why a material failed. 1.1 The primary objective of metallographic examinations is to reveal the constituents and structure of metals and their alloys by means of a light optical or scanning electron microscope. In special cases, the objective of the examination may require the development of less detail than in other cases but, under nearly all conditions, the proper selection and preparation of the specimen is of major importance.

To learn and measure the hardness of the metallographic specimens Abstract Steps of a Metallographic Examination Step 1: Define the Examination Plane. Metallography is a process, and therefore requires different steps and definitions to complete a metallographic examination. The standard in the industry for preparation of metallographic specimens generally referred to is ASTM E3. Introduction …cont.

Additionally, this inspection is used to characterize post processing changes due to casting, forging, machining, welding, heat treating and coating. metallographic examination of specimens allows the metallographer to observe and record the crystalline structures and to interpret from them the history of manufacture and use of the material. Metals and alloys often contain features other than grains.

A metallographic examination performed using the naked eye, or with minimal magnification, is called a macroscopic examination. Using sample preparation techniques similar to those used in microstructure examinations, macrostructural details of a metal are revealed.

Specimen preparation for metallographic examination of medical devices. April 2009. Advanced Materials and Processes 167 (4):51-51. Authors: George Frederic Vander Voort. Vander Voort Consulting Metallography is a destructive testing method which can be conducted in accredited laboratories. For this procedure, experts first prepare the metallic sample to be tested, through sandpapering, polishing and etching. Metallographic examination is then conducted by means of an optical microscope.
