Zirconium alloy shows good combination of strength and ductility, low neutron absorption cross section and excellent corrosion and oxidation resistance. In this study, effect of true strain and feed rates (0.7 m/min, 1.25 m/min and 2 m/min) of rotary swaging process on microstructural behaviour of zircaloy have been performed. Effect of strain and feed rates on surface and centre of swaged and annealed samples were studied using transmission electron microscopy (TEM). Microhardness measurements were performed from edge to centre for swaged and annealed conditions. The swaged samples are exhibiting more deformed microstructure at specimen edge compared to centre location at higher true strain (=0.38), while uniform deformation has been observed in annealed samples. The microstructural inhomogeneities in swaged samples were tandem with microhardness results.
