There is presented results of mechanical properties testing of different type samples from TVEL tubes from Zr-1%Nb alloy. Held investigations with samples tension in tube type and modified samples, shape and dimensions of that are similar with such parameters of ring samples. Held comparison of mechanical properties in longitudinal and transverse directions at standard and modified samples. Notified significant differences of mechanical properties, mostly, relative lengthening (δ%) at testing of modified samples, and also with testing of ring samples with using deformation at cone insertion, in comparison with deformation in axis direction at 2 supports.
