“…This characterization has been performed classically by conventional mechanical test methods as screw-driven or servohydraulic load frames. In the same way, there are some works which have studied the behavior of SMAs at very high strain rates, up to 10 3 s À1 (Adharapurapu et al, 2006;Miller et al, 2000;. Experimental techniques such as the Split Hopkinson Pressure Bar technique (SHPB) or Kolsky bar have been used to achieve these higher strain rates.…”

“…Only a few works deal with the response at very high strain rates in the ballistic range (< 10 3 s -1 ), employing the Split Hopkinson Pressure Bar (SHPB) (Miller et al, 2000;Adharapurapu et al, 2006;Bragov et al, 2006). The characterization in the intermediate range (1 -10 3 s -1 ), has been recently possible (Zurbitu et al, 2009a) thanks to the improvement of the conventional instrumented tensile-impact test which is able to measure with high accuracy mechanical properties at impact strain rates (Zurbitu et al, 2009c).…”

“…However, understanding of the main laws and structural mechanisms of high strain rate deforma tion of these materials remains incomplete without studying their mechanical response to high strain rate tension. The progress achieved in recent years in the modification of the equipment used to perform dynamic tensile tests made it possible to carry out investigations (although insufficient so far) of the mechanical behavior of these alloys under conditions of high strain rate tension [10][11][12][13]. The interest in dynamic extension is mainly related to the instability of the development of deformation, which manifests itself in the formation and propagation of zones (bands) of localized deformation observed upon the tension of polycrystalline NiTi alloys at small rates in both the austenitic and martensitic states [14][15][16][17][18][19][20].…”

The mechanical behavior of the binary polycrystalline NiTi alloy with a quasi equilibrium struc ture has been considered in the course of the high strain rate extension in a temperature range of 20-300°C. The quasi equilibrium structure, which is necessary to ensure the long term stability of special properties of the alloy, was achieved using aging, after which both the forward and reverse martensitic transformations exhibited a multistage character and the phase composition at room temperature was characterized by the presence of R and B19' martensites. To separate the contributions that come from the equilibrium structure and from the high rate of tension to the mechanical behavior of the alloy, a comparative analysis of the dia grams of high strain rate and quasi static tension has been performed. It has been shown that the action of several mechanisms of reversible deformation is determined by the specific features of the equilibrium struc ture, and the level of stresses at which these mechanisms are developed is controlled by the rate of tension. The results of the X ray diffraction study of the phase composition of the alloy samples after high strain rate tension, which make it possible to conclude that the mechanical behavior of martensite and austenite upon the dynamic tension of the alloy is determined by the development of stress induced R → B19', B2 → R, and B2 → B19' transformations and by the processes of the detwinning and reorientation of crystals of B19' mar tensite, are given.
