Laboratory specializing in the microstructural analysis of metallic and non-metallic materials through metallographic preparation and microscopy.

The laboratory is part of a cluster of ISO/IEC 17025-accredited materials testing laboratories (ENAC No. 4/LE063).

Its capabilities include the analysis of heat treatments and surface treatments, phase identification, weld evaluation and PCB microsectioning to detect defects in micro-solder joints.

The main tests and analyses we perform are:

• Macrographic examination (welded joints, fibres, etc.).
• Micrographic analyses:
  - Optical microscopy analysis of all types of materials (microstructure, grain size, determination of non-metallic inclusions, measurement of coating thickness, fibre/resin distribution, micro-sections of electronic components, etc.).
  - Analysis using scanning electron microscopy (SEM) such as fractographic analysis, microstructure, defectology and identification of constituent elements using the Energy Dispersive X-ray Spectroscopy (EDX) technique.
  - Quantification of phases/particles/pores through image analysis.
  - Vickers microhardness testing and determination of the depth of surface heat treatments.
  - Analysis using X-ray diffraction (XRD): Identification and quantification of phases, textures, layer measurement, etc.
• Corrosion testing:
  - Intergranular corrosion testing
  - Pitting corrosion testing

Equipment

• Automatic and semi-automatic optical microscopes with built-in digital camera with up to 1000x magnification.
• Thermoionic scanning electron microscopes (SEM) and field emission electron microscopes (FE-SEM) with EDX microanalysers.
• Software for digital image processing (measurements, grain size, micro-inclusions, phases and casting analysis).
• Automatic Vickers microhardness testing equipment.
• X-ray diffractometer (XRD).
• Stereoscopic magnifying glass with up to 200x magnification.
• Portable device for field metallography.
