Metallography

Macro- and Microscopic Microstructure Examinations

  • In-depth analyzes of the materials and their respective process histories

  • Identification of problems in the manufacturing process, e.g. with respect to casting and forming parameters, heat treatments or the input of foreign material

Our Services

 

  • Preparation and documentation of sections of metallic materials and composite material samples
  • Section analysis according to test standard as well as beyond that so as to be tailored to the respective Task
  • Micromechanical analysis (down to individual phases) by means of Vickers microhardness measurement acc. to EN 6507-1
  • Quantitative determination of particle and cell sizes acc. to ASTM E112
  • Documentation and analysis of samples from forming and heat treatment tests
