APT and TEM study of behaviour of alloying elements in neutron-irradiated zirconium-based alloys

 

Magnified samples from the TEM, at 55nm

Dr Benjamin Jenkins, Dr Jack Haley, Professor Michael Moody and Professor Chris Grovenor have published 'APT and TEM study of behaviour of alloying elements in neutron-irradiated zirconium-based alloys' in Scripta Materialia - Vol 208 (2021).

The paper focuses on the use of Atom Probe and STEM to characterise the effects of irradiation damage in neutron-irradiated Zr-based alloys.  

The key findings include novel observations of the behaviour of Sn, Nb and Fe solutes under irradiation, which may have implications on the macroscopic properties of the alloys.

The work was conducted as part of the MIDAS programme grant.
