“…Regarding the elastic modulus, Ti-Nb-Zr alloys deserve attention for presenting the lowest values, closer to those of bone (≈10-30 GPa), due to the higher amount of the ˇ phase. The ˇ phase has a structure (body-centered cubic) that exhibits a lower bonding force among the atoms, which ensures a reduced elastic modulus [1,47] and favorable plastic deformation capacity of the alloy [45]. This result is in agreement with those of other studies that have found a low elastic modulus in ˇ ternary alloys containing Zr and Nb with different concentrations [6,23,46,48].…”

“…It is postulated that such a grain decrease was very significant, so it was difficult to perform the microstructural analysis by SEM. Nevertheless, regions with light and dark colors representative of solute-rich and solute-poor areas, respectively, can be seen [45].…”

“…For example, while B and Si both have an ability to reduce the grain size, [17,25] these two elements will form intermetallic compounds that may have secondary (perhaps deleterious) effects on the microstructural evolution [24] or the mechanical properties [26] beyond a certain composition limit c 0 . While the overall design of new alloy composition is well beyond this paper, multiple activities are underway [27] to provide tools that can be used in parallel with the emphasis of this paper-affecting grain size.…”

It is necessary to better understand the composition-processing-microstructure relationships that exist for materials produced by additive manufacturing. To this end, Laser Engineered Net Shaping (LENSä), a type of additive manufacturing, was used to produce a compositionally graded titanium binary model alloy system (Ti-xW specimen (0 £ x £ 30 wt pct), so that relationships could be made between composition, processing, and the prior beta grain size. Importantly, the thermophysical properties of the Ti-xW, specifically its supercooling parameter (P) and growth restriction factor (Q), are such that grain refinement is expected and was observed. The systematic, combinatorial study of this binary system provides an opportunity to assess the mechanisms by which grain refinement occurs in Ti-based alloys in general, and for additive manufacturing in particular. The operating mechanisms that govern the relationship between composition and grain size are interpreted using a model originally developed for aluminum and magnesium alloys and subsequently applied for titanium alloys. The prior beta grain factor observed and the interpretations of their correlations indicate that tungsten is a good grain refiner and such models are valid to explain the grain-refinement process. By extension, other binary elements or higher order alloy systems with similar thermophysical properties should exhibit similar grain refinement.

Microstructure and properties of a metastable β-type Ti-35Nb-2Ta-3Zr alloy after cold rolling plus annealing at various temperatures were investigated systematically. The X-ray diffraction results show that the sample annealed at 923 K is mainly composed of the β phase (92.3%). However, the samples annealed at 723, 823, and 1023 K contain a large amount of α phase of 39.6, 36.5, and 39.4%, respectively. The elastic modulus of the sample annealed at 923 K is about 50.1 GPa. However, these of the samples annealed at 723, 823, and 1023 K are 73.7, 56.1, and 70.2 GPa. Furthermore, the sample annealed at 923 K presents the best elasticity and the highest recovery strain (∼66.87%). The corrosion rate of the sample annealed at 923 K (∼2.403 µm•a −1) is the lowest among all the samples, which may be attributed to its minimum content of α phase.
