Scientific Achievement

Pre- and post-silicon infiltrated Si-SiC monolithic ceramics were imaged with neutron radiography.

Significance and Impact

This allows for measuring phases in samples that have uniform contrast with X-rays. This will lead to more informative data in 3D-printed ceramics.

Research Details

  • Bragg edges were identified for the materials
  • Transmission was analyzed and compared to   X-ray data
  • Identifying contrast due to phases was achieved with neutrons
