Ing. Marie Chodurová

Head of the Metalografic laboratory


  • comprehensive control of macrostructure and microstructure, including Baumann imprint
  • microhardness measurement
  • material grade determination and verification
  • etained austenite amount determination
  • testing of corrosion resistance to intergranular corrosion
  • corrosion resistance testing of alloy steels, nickel base alloys, duplex austenitic/feritic steels by means of weight loss
  • determination of delta-ferrite contant
  • detection of defects in welded joints
  • metallographic testing of special alloys based on Ti, Ni, Al, Zn
  • determination of depth of decarburization and heat and chemical-heat treated layers

Except of extensive testing provided in our laboratory, we also provide investigation right at the customer’s premises without need of the tested product destruction:

  • microstructure (by means of replica technique, that means imprint of microstructure on a collodion film)
  • hardness measurement using a rebound hardness tester

Testing of ferrous and nonferrous metals and their alloys and of weld joints is performed according to the EN, ISO, ASTM, ASME, GOST standards and the customers´ requirements.
