Laboratories of Materials Engineering and Metallurgy:
Laboratory of Mechanical Properties of Materials
The successful performance of metals in meeting design requirements, specific working conditions, and the ability to produce them in the proper dimensions largely depend on their mechanical properties, which are used in mechanical tests to evaluate these properties. The Mechanical Properties Laboratory of Materials Engineering and Metallurgy Department of Urmia University of Technology is equipped with a universal tensile testing machine with a capacity of 3 tons for drawing nonferrous and nonferrous metal samples (including round and flat samples). Bending and pressure tests are also performed by this machine. In addition, the laboratory is equipped with a 300-kW impact tester to evaluate the impact performance of various metal samples. Macro hardness tests by Brinell, Rockwell and Wickers methods as well as micro hardness tests are other capabilities of this section.
Metallography means studying the internal microstructure of metals. In the Metallography Laboratory of the Department of Materials and Metallurgy Engineering of Urmia University of Technology, the structure of metals and alloys at the micro and macro scales is investigated using light microscopes. Comparison of these results with relevant standards helps to predict mechanical and physical properties, to investigate structural and surface defects. These analyzes are used to estimate the useful life of components, investigate the causes of failure, and reverse engineering. The main activity of this laboratory is divided into two parts: macrography and micrography. In practice, the macrographs of the structure of metals, alloys, and materials in general are examined in a way that is visible to the naked eye or to a low magnification. For this purpose, the sample surface is first polished by sanding operations with different numbers from coarse to fine and then etched with special chemical solutions. These chemical agents dissolve the phases on the metal surface and identify its various components, holes, cracks and other disadvantages. Macrographic examination includes welding sections and ingots, examination of material flow lines, etc. Micrographic section aimed at studying and understanding the internal structure of materials in terms of grain size, grain boundaries, grain distribution and metal forming phases. In this laboratory it is possible to enlarge test samples from 0 to 1000 times. Examination of microscopic structure including preparation and interpretation of light microscope images of existing phases, determination of volume percentages of phases, examination of microscopic defects (inclusions, cavities, cracks, etc.), determination of grain size, determination of coating thickness and quality, determination of heat treatment, and ... in ferrous metal (steel and cast iron) and non-ferrous (aluminum, copper, magnesium, etc.).
