Zeiss SIGMA installed at IEHK


Modern steels show complex multiphase microstructures on a nanosized length scale. For the advanced microstructure characterization a fast quantification in terms of local morphology, crystal orientation and chemical composition is needed.

Since April 2014 IEHK is operating a Zeiss SIGMA Field Emission Scanning Electron Microscope (SEM) in combination with Oxford Electron BackScatter Diffraction (EBSD) and Energy Dispersive X-ray Spectroscopy (EDX). The investment was realized within the framework of Aachener Center of Excellence “Integrative Production Technologies for High Wage Countries”. Future work will focus on the automatic quantification of phases with substructure (eg bainite), the advanced structure properties relationship in High Manganese TRIP and TWIP steels and the detailed evaluation of martensitic steels from rapid and ultra-rapid metallurgy processes (eg Selective Laser Melting).

Funding within the frame of RWTH Aachen Cluster of Excellence

  • Zeiss SIGMA – Field Emission SEM
  • Oxford EBSD+EDX System

In operation in cooperation with MCh since March 6th 2014:

  • Morphology (SEM), crystal orientation (EBSD) and chemical characterization (EDX) of nano structured, multiphase complex steels
  • Object Oriented Picture Analysis based for Bainitic Structures
