  • SEM can be utilised to take highly detailed images of areas of interest on a sample (e.g. – fracture surfaces, contamination, etc).
  • The EDX detector can be utilised to determine the elemental profile of the area under investigation (e.g. – elements present in material to defined steel type)

Mechanical properties – Tensile, Compression, Flexural and Friction analysis

  • ISO testing on standard specimens or custom made samples
  • Tensile testing to measure material strength and elongation (flexibility).
  • Compression testing
  • 3-point bend flexural testing to measure flexural strength and modulus (stiffness).
