ORNL Review


Vol. 45, No.3, 2012

 

Neutron scattering facilities provide unique microstructural characterization tools

 

High Flux Isotope Reactor:

  • (1965 - present) World-class steady-state neutron source

Spallation Neutron Source:

  • World-class pulsed neutron source

Non-destructive residual stress mapping:

  • Applicable to most engineering materials
  • Validation of finite element models

Crystal structure characterization:

  • Bulk rather than surface information
  • Sensitive to light elements (O, N, C, H)
  • In-situ high-temperature studies

Small-angle neutron scattering:

  • Measurements at nano- and meso- scale
