Materials for Nuclear Power Systems

A single phase hexagonal close packed Zircaloy 2 was cold deformed to different reductions by laboratory rolling. Systematic characterisations of the structural developments were carried out. Bulk texture developments were gradual, strongest developments being noticed at the highest strain. Although formation of well defined deformation fibre(s) could not be identified, overall developments in deformation texture were best captured through Taylor type models incorporating only prismatic slip. Strain localisations were observed as single or double walled dislocation structures at approximately 45 and 60° to the rolling direction. Such strain localisations were always associated with significant lattice reorientations or misorientation developments. Relative softening in lattice strain, observed at the higher reductions, can possibly be explained by the appearance of extensive strain localisations and the associated concurrent local dynamic recovery. The grains or orientations with dominant presence of strain localisations could be indirectly related to negative textural softening.

C. O. Smith London: Addison–Wesley Publishing Co. Inc. 1967 Pp. viii + 262. Price £5 8s. This book is based upon notes developed and used by the author to teach the course on reactor materials at the Oak Ridge School of Reactor Technology. The material presented embraces the entire field of nuclear engineering and it is inevitable therefore that no subject is entered into to any great depth.
