Case Studies

Materials & Components

Neutrons can be used to study materials and components, as for instance:

  • Non-destructive Stress scanning: investigation of engineering size component, study of surface treatment
  • Non-destructive radiography and tomography (organic material , water, Hydrogen or Lithium visible after several centimeter of metal)
  • Trace element analysis
  • In-situ follow-up of alloy formation
  • Investigation of metals, alloys, glasses, ceramics, semiconductors, composites, nanomaterials 
  • Irradiation tests (hardening, shielding, single event upset)

High-strength Aluminium Alloys: investigating stresses for improved casting

High-strength Aluminium Alloys: investigating stresses for improved casting

High-strength Aluminium Alloys: investigating stresses for improved casting

Due to the excellent ability of neutrons to penetrate metals, it is possible to measure deformation within a component non-destructively by observing diffraction peaks. A study was conducted to compare two aluminium ingots produced by direct chill casting but subjected to different cooling processes.

Investigation of residual stresses in new materials for the development of aircraft turbines

By using neutron diffraction, the residual stress distributions in a water-quenched IN 718 compressor disc were studied. This knowledge allowed an optimization of subsequent treatments such as turning to final shape to minimize unwanted effects of distortion and deformation.

Performances of Li-ion battery: investigating lithium ions movements

Neutron diffraction is an excellent technique for monitoring lithium ions moving through the electrodes, because neutrons are readily scattered by light elements such as lithium (unlike X-rays).

Thanks to neutrons, it was demonstrated that the local water content in the membrane is not directly correlated to the water content in the surrounding channel.

Results from neutron measurements provide unique information that can be used to optimize the design of the next-generation of high performance fuel cells.
