mechanical-metallographic laboratory

The mechanical-metallographic laboratory is equipped with state-of-the-art equipment that enables a large range of testing, both mechanical and microstructural characteristics of metal materials and welded joints.

metallographic tests

  • LEICA DM4 M is a specialized metallurgical microscope with a magnification of up to x2000. It is ideal for observing welded metal joints, measuring grain size and shape as well as the content of non-metallic inclusions.
  • LED illumination contributes to the reproducibility of results – whether working in bright field, highly dynamic dark field, differential interference contrast, fluorescence or polarization.
  • Thanks to excellent software, the microscope automatically recognizes the selected contrast technique and the object in use. It precisely opens and closes the aperture and field diaphragm and thus adjusts the light intensity.

tensile, bending and compression testing (shimadzu ag-x)

  • Universal machine for tensile, compression and bending testing. The maximum force during testing is 300 kN, while the speed range at which experiments can be performed is from 0.0005 mm/min to 500 mm/min, where the load can be set continuously and cyclically.
  • The maximum opening of the traverse with clamping jaws is 450 mm and the dimensions of the sample that can be tested are:
  1. For samples with a rectangular cross-section:

W:0-50 mm, L:0-25.5 mm

2. For samples with a circular cross-section:

Diameter: 4-30 mm

determination of micro and macro hardness of metals and welded joints

  • Willson VH1150 and VH1102 are machines for testing macro and micro hardness of materials according to Vickers. The load range that this machine can set is from 0.3 kgf to 50 kgf or 0.01 kgf to 2 kgf. The height of the sample is up to 210 mm and the width is up to 160 mm for macro or height 130 mm and width 130 mm for micro testing.
  • Echo LAB HB 625 Z hardness tester is a machine for testing the hardness of materials according to Brinell. The test forces range from 49.03 N (5 kg) to 612.9 N (62.5 kg). The hardness testing range ranges from 8 to 650 HBW. The sample height is up to 170 mm, and the width is up to 130 mm.
  • Wilson BH3000 is a machine for testing the hardness of materials according to Brinell. The load range that this machine can apply ranges from 62.5 kgf to 3000 kgf. The sample height is up to 280 mm, and the width is up to 130 mm.

impact toughness testing using the Charpy pendulum method

  • The echoLab Charpy pendulum enables precise and computer-based determination of the impact toughness of metals up to 450J at room and low temperatures down to -60 degrees Celsius.
