Retained austenite quantification by energy dispersive X-ray diffraction (EDXRD)

Area of expertise

Fatigue of components and structures

rayon X

Energy dispersive phase analysis


YOUR EXPECTATIONS

 

You would like to quantify the amount of retained austenite in order to:

 

  • Develop or test a manufacturing process
  • Compare several manufacturing processes
  • Develop new products
  • Develop new heat and thermo-chemical treatments
  • Analyse parts after failure
OUR SOLUTIONS

 

Techniques:

 

  • Energy dispersive X-ray diffraction (EDXRD)
  •  Quantification carried out from the measurements of the intensities of the constituent phases of the materials. For example – thermo-chemical treatment of a steel: 16 α phase (ferrite, bainite and martensite) and γ phase (austenite) reflections
  • Totally automatic quantification and analysis
  • Length of time for acquiring then processing results ranges from 10 min to 30 min maximum according to the samples (24 hr as required in standard method)

 

 

 

Characteristics:

 

  • Analyses of all types of steel and iron (even textured and containing carbides)
  • Contents between 0% and 100%
  • Analysis repeatability currently less than 0.5%
  • Determination of strain-induced martensite in austenitic steels
  • Additional information on the structure (strain-hardening, lattice parameter)
  • Characterisation of layer thicknesses
YOUR BENEFITS
  • Comprehensive management of your experiment requirements
  • Meeting deadlines with results in less than 48 hours
  • Response adapted to the requirements of your customers
  • Assurance that analyses can be repeated
  • Availability of accredited expert laboratories (accreditation Cofrac - No. 1-1014 - Scope available on www.cofrac.fr)
