Characteristics of Shape Memory Effect in Commercial Titanium Alloy VT16

Abstract—The structural features and thermomechanical behavior of VT16 alloy specimens subjected to annealing in the β-region followed by quenching from the (α + β)-region are investigated. To achieve the shape memory effect, the test specimens were upset by the amount of residual deformation from 2.2 to 3.8%. It was found that when specimens are heated in the temperature range from 45 to 250°C, a partial shape recovery (from 1.1 to 0.8%) occurs due to reverse martensitic transformation and when the temperatures exceeds 270°C, deformation accumulates due to the diffusive decomposition of the β phase.
