Metallography Laboratory

Due to the presence of metal parts lab and in order to provide services in the selection of metal materials, the selection of production methods and the selection of physical and mechanical properties, optimization and reverse engineering of parts in the company, structural analysis of images prepared from the prepared surfaces of parts Different is possible. These components include iron and non-ferrous metals with various applications in the automotive industry. Structural analysis can provide engineers with prediction of strength, toughness, hardness, thermal corrosion resistance, abrasion resistance, and also the prevention of failure and early corrosion in industries, especially in cases where due to the size and size limitation or because of the impossibility of the sample The vector does not have any mechanical research attempts to destroy the sample. Also, the analysis of fracture surfaces or corrosive surfaces can help the experts identify corrosion or failure prevention methods. At the laboratory, metallurgical experts have the ability to study the microscopic structures of metallic materials, both iron and non-ferrous. Microscopic and macroscopic examinations are performed by optical and stereo microscopes in different magnifications (25 to 1000 times), and are performed by Image Analyzer software. The Image Analyzer software is able to calculate the fractional percentages of phases, the size of the grains, the thickness of the coating, the size and distribution of graphite in the cast iron, the degree of distinction between steel and the degree of impurities. It is also possible through structural analysis, determination of the process of production of parts and determination of the thermal operation cycle applied to parts for the purpose of reverse engineering. In addition to conducting metallographic tests, the hardness of the metals is also carried out in this laboratory. Due to the high speed of the test and the lack of long-term preparation, hardness testing is a quick method for determining the mechanical properties of the parts. Also, the hardness of metals can be used to control and recognize the correct microscopic and macroscopic structures, as well as to determine the heat treatment cycle used on the parts. Hardness testing test is possible without the need to demolish the piece on the surface of the parts. Hardness tests are used for a wide variety of metals, depending on the variations, scales and forces employed. Hardness tests can be done depending on the type of alloy, dimensions, mechanical and physical properties on different scales. Also, hardness is a reference method for determining the depth of a hardened or de-hardened layer in steels and castings.
