Metallographic micrograph analysis

  • sample preparation
  • generation of component specific cross sections
  • application of a range of microscopic techniques (use of light microscope, laser scanning microscope, scanning probe microscopy (SPM), etc. )
  • investigations on materials and materials compounds, on components of all sizes from the macro to the micro scale
  • damage or failure analysis
  • reports and evaluations of
    • materials structures
    • microstructural changes
    • existing damage
    • deformations
  • determination of real geometries in selected materials preparations for use as FE-simulation input data
  • determination of topographic parameters
