Residual stress determination

 From X-ray diffraction to incremental hole drilling

Your expectations

You want to determine residual stresses in order to:

  • Develop or test a manufacturing process:
    - Raw part
    - Heat or thermo-chemical treatment (tempering, case hardening, etc.)
    - Machining (grinding, milling, turning, etc.)
    - Work treatment (shot peening, roller-burnishing, etc.)
  • Compare several processes concerning fatigue strength or stress corrosion.

Our solutions

Definition and implementation of suitable protocols:

  • Advice and support for developing an experimental design
  • Assistance in drafting specifications

 

Surface or in depth analysis:

  • X-ray diffraction method (non-destructive)
  • Incremental hole drilling method (destructive)

 

Working with large instruments:

  • Neutron radiation method (non-destructive)
  • Synchrotron radiation method (non-destructive)

 

Assistance in exploiting and capitalising on the results.

Your benefits

  • Comprehensive management of your experiment requirements
  • Project monitoring adapted to your demands
  • Standardised tests (EN15305-2009 and ASTM E837-2008)
  • Services of a provider with proven skills (35 years of capitalising on experience) that is certified both by approved organisations (ISO 9001) and its customers (Safran, Airbus, Renault, PSA, etc.)
