Equipment of the laboratory

  • Nikon and Carl Zeiss microscopes (50× – 1000× magnification), a fully-automatic motorized stage (for photographing large areas extending beyond a single field of view), software for digital processing of image and image analysis
  • Durascan automatic microhardness tester (Vickers scale HV 0.01 – HV10)
  • Instrumented nanoindentor - NanoTest Vantage: Load range: from 10 μN to 500 mN (resolution 3 nN)
  • JEOL scanning electron microscopes
  • Detectors: secondary electron (SE) detector, backscattered electron (BSE) detector, INCA detector for energy-dispersive spectrometry (EDS) from Oxford Instruments and HKL NORDLYS EBSD high-speed camera
  • Other equipment: ion-beam polisher for preparing specimens for scanning electron microscopy – analysis of grains and subgrains, low-angle and high-angle grain boundaries and texture and crystallographic identification of phases
Grains Weld
Microstructure of quenched and tempered steel etched to reveal prior austenite grain boundaries
