The effect of metastable austenite straining on the basic functional properties of an NiTi alloy in quasi-equilibrium state was studied. Straining of austenite in a pre-martensitic state was shown to result in improvement of one-way and two-way shape memory effects (OWSME and TWSME). This improvement took place after straining in a narrow temperature range, and its manifestation at quasi-static and high-rate tensile tests was different: the increment of both characteristics was sufficiently large after quasi-static straining, but smaller after high-rate straining. Straining at temperatures that deviated significantly from the M s temperature led to deterioration of OWSME and TWSME. |
