In this laboratory a section a chair arm that had broken off was selected for examination. The specimen was cut, The effect of substrate on metallographic corrosion of cladding in stainless/carbon steel bimetal plate is investigated in this paper. The metallographic observation results show that the presence 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. Metallographic Examination – Optical Consists of preparing a sample by sectioning, grinding, polishing, etching and subsequently examining under Metallography allows the metallurgist to determine certain characteristics regarding the material, such as quality and 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). Metallographic examination is complex of tests and analytical measures aimed at studying macrostructure and microstructure of metals, studying consistencies of structure generation and establishing dependencies of the structure impact on mechanical, electrical and other properties of the metal.

Further, certain features can be best observed with the LOM, e.g., the natural color of a Metallographic preparation of titanium and titanium alloys. Titanium is a highly ductile metal, which makes it difficult to cut, grind and polish in preparation for microscopic observation. This guide outlines the most effective ways to prepare titanium and titanium alloys for metallographic examination, with accurate and reproducible results. Metallographic analysis of the shaft indicated poor metallurgical quality of the steel.

Metallographic examination is complex of tests and analytical measures aimed at studying macrostructure and microstructure of metals, studying consistencies of structure generation and establishing dependencies of the structure impact on mechanical, electrical and other properties of the metal. Metallographic examinations are used in a variety of ways in damage analysis. Classic metallography consists of cutting sections through the sample, embedding it in synthetic resin, grinding and polishing the surface until it is smooth. This allows the observation of very fine structures under the light-microscope with a magnification of up to Macroscopic examination techniques are frequently employed in routine quality control,infailure analysis, and in researchstudies. Thesetechniquesare generally a prelude to microscopic examination; however, in quality control, they are often used alone as a criterionfor acceptance or rejection.

Abstract. Proper preparation of metallographic specimens to determine microstructure Metallurgical Testing typically uses microscopy to provide important information about the structure and properties of metal and alloy samples. These services are Precision Metallurgical Sample Preparation, also called Metallographic Specimen Preparation, is a key step in performing reliable metallurgical testing. 4.2 Many specifications contain a requirement regarding microstructure; hence, a major use for metallographic examination is inspection to ensure that the 31 May 2012 Metallography relates to the methods of studying structure of metals and alloys: Macro- (Macrography, Macrostructure) Examination is a method On-site metallography or metallographic replication is a non-destructive testing method to evaluate the metallurgical condition of a metallic component.

Metallographic examination is typically performed on polished cross sections, which may be etched to bring out the structure of the material by selectively corroding grain boundaries.
