The evolution of microstructure and texture after final annealing treatment of two kinds of zirconium-based alloys with different composition (Zr-Nb, Zr-Sn-Nb) was investigated by electron backscatter diffraction (EBSD). The misorientation of the recrystallized grains was characterized. The results show that the grains of the alloys after final annealing treatment are uniform and equiaxed, and most of the grain sizes range from 2 to 5 μm; the second phase particles (SPPs) are very different for the two kinds of alloys. The SPPs disperse evenly in Zr-Sn-Nb, while in the Zr-Nb, there are two kinds of SPPs. The main texture of the alloys after final annealing is the basal texture, and the maximum is spread out towards the transverse direction. And the < > directions are parallel to the rolling direction.
