Abstract
The coupled temperature–strain rate sensitivity (SRS) of Ti–29Nb–13Ta–4.6Zr β-type Ti-alloy has been studied. The martensitic transformation is identified as the main reason of negative rate sensitivity during deformation at room temperature and 100 °C. In addition dynamic strain aging (DSA) is in charge of further decrease in SRS values at temperatures higher than 100 °C. The SRS values start increasing beyond 200 °C due to dissipating the DSA effects. This finally reaches the positive domain due to domination of dislocation slip.
