GWP offers highly specialized investigations of material structures using light microscopy on etched sections. By using various metallographic etching processes, the microstructure of a material becomes visible and enables detailed insights into its properties.
With extensive experience in preparation and metallography, GWP can analyse and interpret a wide range of material structures. For stainless steel samples, for example, colour etching can be carried out using the method of Lichtenegger & Bloech This etching process makes it possible to remove important structural components such as the primary structure (segregations), the secondary structure (austenite with twinning) and the delta ferrite content to make visible and evaluate.
This method of light microscopy is particularly useful for comprehensively understanding the properties of a material and identifying quality-relevant characteristics, such as susceptibility to corrosion or strength. GWP's expertise in this area ensures that the microstructure assessments are carried out precisely and in a well-founded manner.
