Materialography is the examination in both the macroscopic and microscopic range for visualising and detecting internal structures of metals, ceramics and plastics. Analytics serves for determining the chemical composition of materials or their structural constituents.  

Within the GSI we mainly work on the field of metallic materials (metallography). In doing so, the metals steel, cast iron, nickel, copper, titanium and aluminium are within our focus.
We offer among others the following examinations within the scope of quality assurance and investigations on damage:

• Macroscopic and microscopic examinations on the most various materials with and without auxiliaries such as macroscope, microscope, scanning electron microscope within the range 1:10 to approx. 10000:1.
• Determination of material structures, documentation, evaluation of the structures according to different terms and regulations such as grain size, degree of purity, type of structure, and portions.  
• Hardness tests in the range of HV 10 to HV 0.2.
• Analysis of metallic materials (steel, aluminium, copper, nickel) using spectroscopy.
• Scanning electron microscope including energy dispersive, qualitative micro-analysis.
