Metallography

In the laboratories of NII Stali the following types of analyses of different materials (irons, steels, non-ferrous metals and alloys, ceramics and composite materials) can be performed:

• chemical and spectral analysis of the material composition;
  
• stress-strain properties test:
       - tensile and bending test in the temperature range of +20 to +150°C;
       - toughness test in the temperature range of -180 to +120°C;
       - Brinnel, Vickers and Rockwell hardness tests.
  
• Metallographic macro- and microstructure examination:
       - grain size measurement;
       - qualitative and quantitative analysis of nonmetallic inclusions;
       - evaluation of carbon and other inhomogeneity of materials.
  
• Nondestructive inspection of surface and internal defects of materials by capillary or radiographic methods.
  

Expert examination of different materials can be performed by methods of transmission and scanning electron microscopy, X-ray phase analysis etc.
