Abstract

In situ synchrotron X-ray diffraction was used to study the deformation behavior of a Ti-17Nb-1Cr alloy at room temperature. Stress-induced martensite (SIM) transformation increased the total recoverable strain. A maximum of ∼3.5% strain recovery was obtained after proper heat treatment. Unlike other alloys with a bcc crystal structure, the β-phase has a strong (210)_β texture, supporting the previous suggestion that all meta-stable β-Ti alloys may have a similar texture instead of the well-known (110)_β texture after axisymmetric deformation. The ω-phase has a (22.43)_ω texture. The (041)_α_″ fiber texture in α″-phase was formed from the (210)_β texture based on their crystal orientation relationship.
