摘要

Abstract—The effect of aging conditions at temperatures 370 to 550°C on reverse martensitic transformation stages and deformation-temperature characteristics of the one-way shape memory effect for a Ti–55.6Ni alloy (wt %) has been investigated. The test method was based on the ASTM F2082 standard. The variation martensitic transformation stages, increased recovered deformation, and increased shape recovery temperature in aged specimens are shown to be associated with the release of the Ti3Ni4 phase, which depleted the B2-phase of nickel and increased the level of microstresses. The maximum rise in shape recovery temperatures (up to 45–50°C) results from aging at 400 to 460°C.
