Grain size, orientation, phase precipitation, and metallurgical structure changes are carefully analyzed. This method plays a critical role in the quality control of heat-treated or specially alloyed metals. It is used to evaluate the long-term effects of microstructural changes on mechanical strength.

Replica examination, performed according to ASTM E1351 and EN 10247 standards, allows the surface microstructure of large and fixed equipment to be analyzed without sampling. ASTM E1351 This method eliminates the need for sample extraction and enables the evaluation of changes in material structure, deformation, and service life. It is particularly useful in energy plants, chemical facilities, and equipment that operates at high temperatures.

The Z-quality test, conducted according to EN 10164 and ISO 377 standards, helps assess the mechanical behavior of materials in the thickness direction and identify risks of delamination. EN 10164 This test is used to evaluate the mechanical properties in the thickness direction and assess the risk of layer separation, especially for thick plates and large castings. It is used to assess the three-dimensional load-bearing capacity of materials.

The flattening test, performed according to ASTM A370, ISO 8492, and EN 10233 standards, is a critical analysis to measure the mechanical strength and deformation capacity of pipes. ASTM A370 / ISO 8492 This test measures the deformation capacity and mechanical strength of pipe samples when subjected to a specific force. It is used to verify the suitability of pipes for cold-forming processes and assess the production quality of welded pipes.

The nut stripping test, conducted under ISO 2320 and ASTM F606 standards, verifies the load-bearing capacity and thread resistance of bolt connections. ISO 2320 This test evaluates thread deformation and mechanical strength in nut connections. It is particularly important in quality control for high-strength bolt connections, used to determine whether connection components can withstand the loads they are exposed to during assembly.

ASTM E415 / ASTM E1086 This test uses a spectrometer device to accurately determine the chemical composition of materials. It is used to verify the content of elements such as carbon, manganese, chromium, and nickel in metallic materials, ensuring their compliance with quality standards.

Fatigue testing is a critical test method used to evaluate the durability of materials under repeated loading. These tests are used to determine the fatigue life of a material over long-term use and prevent fracture or crack formation.
