“…The texture mostly influences the properties of ȕ-Ti alloys and the textured alloy specimens present the anisotropic tensile properties. The same conclusion was made in Ref [14,15], for Ti-29Nb-9Ta-10Zn alloy. Also, in that works it was shown that formation of a bimodal microstructure consisting of a parent ȕ-Ti phase and a stress/thermal induced ĮƎ-Ti phase, leads to a lower elastic modulus.…”

“…The influence of the mechanical treatment on the phase transformations and mechanical properties of the obtained samples from the Ti based alloys have been already studied [12][13][14][15][16][17][18][19][20][21]. For example, as it was shown for the Ti-25Al-XNb (here mass %) alloys [12,13], the texture orientation, acquired during the plastic deformation by rolling and subsequent heat treatment, influences the mechanical properties of the Ti-based alloys.…”

“…A suitable thermomechanical processing route is a key issue in obtaining adequate microstructures containing a favorable phase combination to achieve a final desired combination of properties, i.e., low elastic modulus and suitable mechanical properties together with corrosion resistance and biocompatibility. It was proven that a bimodal microstructure consisting of a mixture of β-Ti and α"-Ti phases, with an increased α"-Ti phase fraction can lead to a structural state exhibiting a lower elastic modulus, due to the lower elastic modulus of the α"-Ti phase in comparison with the β-Ti phase [19,20]. Constituent phase fractions can be manipulated by thermomechanical processing to adequately steer the mechanical properties towards the desired values.…”

The effects of heavy cold plastic deformation by rolling on microstructural features and mechanical properties of Ti-25Nb-6Zr-1.7Fe (wt %) biocompatible alloy (TNZF) were studied. After a preliminary alloy processing, a heavy plastic deformation by cold-rolling (CR) with a total relative degree of plastic deformation of 90% (equivalent plastic strain, ε = 2.42) and a subsequent solution heat treatment (CR+ST) at 900 • C for 0.6 ks/water quenching were applied and then investigated. The CR and CR+ST states have microstructures consisting of mixtures of β-Ti phases and α"-Ti. The alloy in CR state shows a pronounced deformation texture, with highly deformed and elongated β-Ti grains, exhibiting internal highly fragmented areas, with shear lines at about 45 • and a sub-micron/nanocrystalline fine dispersed α"-Ti phase. The alloy in CR+ST state has completely recrystallized equiaxed polyhedral β-Ti grains, with average grain size close to 52 µm and a sub-micron/nanocrystalline fine dispersed α"-Ti phase. Recorded mechanical properties, for both CR and CR+ST states, show quite similar values for the yield strength (σ 0.2), ultimate tensile strength (σ UTS) and Vickers microhardness (HV0.1) for CR state (σ 0.2 = 603 MPa, σ UTS = 1282 MPa and 287 HV0.1) in comparison with CR+ST state (σ 0.2 = 598 MPa, σ UTS = 1256 MPa and 256 HV0.1). Values for the modulus of elasticity (E) are lower (E = 72 GPa for CR state and E = 61 GPa for CR+ST state) than those for conventional biocompatible alloys (E~110 GPa).

Anisotropy of the Young s modulus and microstructure of a recrystallized β Ti-Mo-Al-Zr alloy with a Goss texture were investigated. Specimens were solution-treated at 1173 K for 3.6 ks after cold rolling with a reduction rate of 99%. The {011}<100> Goss recrystallization texture developed as a major texture component. The Young s modulus was evaluated by tensile tests using a strain gage method. Anisotropy of the Young s modulus depending on the loading direction was observed: The lowest and highest values of the Young s modulus were 44 and 77 GPa, respectively. The compliance anisotropy factor, J, and the characteristic modulus, S 11 , of the alloy were calculated from the measured Young s moduli and the volume fractions of the texture components.
