Texture evolution in TLM titanium alloy during uniaxial compression

In this work the texture evolution of a near β Ti-3Zr-2Sn-3Mo-25Nb (TLM) biomedical titanium alloy in cold compression has been investigated. The XRD examination shows that the resultant samples consist of β together with a small amount of the stress induced martensitic (α″ phase. The development of texture has been explained in terms of orientation distribution functions (ODFs) of α and γ fibres. Comparing with other β alloys such as Ti-15V-3Cr-3Sn-3Al and Ti-10V-4.5Fe-1.5Al, the texture in the TLM alloy changes continuously with the increase of compression reduction; specifically, the texture components of the starting material change once the compression reduction is up to 5%, and the prominent texture component of {111}〈110〉 recovers and the orientation density starts to increase when the reduction increases from 10% to 50%.
