This lecture discusses the sample preparation techniques used to get the sample ready for imaging.

Metallographic examinations allow to get details about the microstructure of the material, like grain size, presence of non-metallic inclusions, phase concentration and other characteristics influencing the properties of the material. Sider Test performs these tests according to accredited testing methods (ISO 17025).

make sure that the prepared sample has a flat, scratch-free and mirror-like surface [2]. 2 Steps of Metallographic Sample PreparationMain steps of sample preparation include: Rough grinding Mounting Intermediate polishing Fine polishing Etching 1Rough Grinding:The sample should be of a size that is easy to handle during grinding and polishing There are two examination methods in metallography: I) Macroscopy 2) Microscopy In macroscopy the examination of the structural characteristics or chemical characteristics of a metal or an alloy is done by the unaided eye or with the aid of a low-power microscope or binocular, usually under l0x. When a destructive examination of static equipment, piping, etc. cannot be performed, the replica technique offers an interesting solution to perform a metallographic examination in situ.

Using sample preparation techniques similar to those used in microstructure examinations, macrostructural details of a metal are revealed. Typically, a full cross-section of a part is examined. Metallographic Analysis – Metallurgical analysis (metallography) of the microstructural provides the Material Scientist or Metallurgist information varying from phase structure, grain size, solidification structure, casting voids, etc. Figure 2 shows an example of two cast iron structures.

Metallographic examination is then conducted by means of an optical microscope. Metallographic examination has become an indispensable tool in the testing, quality control, failure studies and post-mortem analyses of these devices.

Metallurgical Testing Know Your Material’s Structure & Weaknesses. Metallurgical Testing typically uses microscopy to provide important information about the structure and properties of metal and alloy samples.These services are also called Metallography Evaluation, Metallographic Examination and Metallurgical Analysis.

Learn all you need to know about micro and macro examination of welded joints – from cutting and mounting through to etching and inspection – with expertise and insight from Struers, the world’s leading materialographic and metallographic experts.

October 11, 2016 5 Metallographic examination can also be performed on site by means of the replica testing method. Results are then analyzed in the mobile TÜV lab vehicle. Also called in-situ metallography, replica testing is a procedure that consists in reproducing the microstructure of a metal’s surface. We Offer Metallographic Examination, Metallographic Examination Lab, Metallographic Examination Laboratory, Metallographic Examination Services, Metallographic Examination Providers in Dombivli, Thane, Mumbai, Navi mumbai, India.

There are two examination methods in metallography: I) Macroscopy 2) Microscopy In macroscopy the examination of the structural characteristics or chemical characteristics of a metal or an alloy is done by the unaided eye or with the aid of a low-power microscope or binocular, usually under l0x.

Experimental fatigue strength testing of conventionally cast tool steels and a Metallographic and fractographic examination of fatigue loaded This International Standard covers examination of samples that have previously been exposed to corrosive environments at high temperatures.

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. Such features include pores 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. Metallurgical Testing typically uses microscopy to provide important information about the structure and properties of metal and alloy samples. These services are also called Metallography Evaluation, Metallographic Examination and Metallurgical Analysis. 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.
