Crystallographic Phases, Texture and Dislocation Densities of ZR2.5%NB Pressure Tubes at Different Stages of Manufacturing

Neutron diffraction experiments have been performed on specimens produced from Zr2.5%Nb pressure tubes, in order to characterize the crystallographic phases, texture and dislocation densities at different stages of a new manufacturing schedule developed in Argentina. Experiments were performed on ENGIN-X a time-of-flight neutron strain scanner at the Isis Facility, UK, using an optimized measurement strategy that exploits the well-known crystallographic texture of the pressure tubes.
