The results of studies on the deformation behavior during quasistatic tension of zirconium-based alloy samples (Zr-1 wt.% Nb) in microcrystalline and ultrafine-grained states are presented. The patterns of strain field distributions on the surface of the samples under tension have been obtained using a three-dimensional digital optical system Vic-3D. It has been established that the deformation difference in the plastic strain zone relative to the deformation, averaged over the entire sample, depends on the structural state of the Zr-1Nb alloy at the stage preceding destruction of the samples. Based on the analysis of the distribution patterns of strain fields, the Poisson's ratio and the Gruneisen parameter in the plastic strain zone have been determined.
