“…The first Ti alloy to combine Ti-specific biocompatibility properties with mechanical properties at least as good as those of conventional materials is the Ti-6Al-4V alloy [ 17 ]. It is one of the most widely used titanium alloys in medicine, it has low wear resistance, a high modulus of elasticity (about 4–10 times higher than human bone), and a low shear strength.…”

Metals that come into contact with the body can cause reactions in the body, so biomaterials must be tested to avoid side effects. Mo, Zr, and Ta are non-toxic elements; alloyed with titanium, they have very good biocompatibility properties and mechanical properties. The paper aims to study an original Ti20Mo7ZrxTa system (5, 10, 15 wt %) from a mechanical and in vitro biocompatibility point of view. Alloys were examined by optical microstructure, tensile strength, fractographic analysis, and in vitro assay. The obtained results indicate very good mechanical and biological properties, recommending them for future orthopedic medical applications.

“…Some Ti alloys with low elastic modulus designed through [Mo] eq are shown in Table 2. [19,31,33,34,36,102,103,[107][108][109][110][111] Results show that the elastic modulus of Ti alloys is not only related to the [Mo] eq value but also concerned with the category of alloying elements. Therefore, the [Mo] eq models are efficient in the screening composition of certain Ti alloy systems.…”

“…Other low-Young's-modulus Ti alloys containing alloying elements that should have negative effects when they are excessive in the body are also collected and shown in Figure 3. [15][16][17][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] Although the elastic modulus of existing Ti alloys is very close to the maximum value of biological bone, the development of cheaper and lower-modulus Ti alloys is still one of the most important research directions of biomedical implant materials.

“…In our previous work, an as-cast Ti-11.8Mo alloy designed using a cluster plus-glue-atom (CPGA) model was developed. 7 The model had the formula [Mo(Ti 14 )]Ti 1 , which consisted of the cluster part [(center atom)-(shell atoms) 14 ] and the glue atom part, (glue atoms) x . The position of elements in the formula was based on their interaction, which is characterized by their enthalpy of mixing (∆H).…”

The effect of Nb in the glue site of the cluster-plus-glue atom model formula on the microstructure and mechanical properties of Ti-Mo alloy was investigated. Phase and microstructural analysis were performed by X-ray diffraction and electron backscatter diffraction. Tensile properties were also examined. A small amount of secondary martensitic α” and ωath nano particles were precipitated in the β matrix of both alloys, due to to the inhomogeneous distribution of Mo and/ or Nb caused by segregation, which formed local regions with high- and low-stability of the β phase. The elastic modulus was significantly reduced to 56.9 ± 3.08 GPa, while the elastic admissible strain was substantially improved. The increased β stability and suppression of the ωath phase led to no significant change in both the yield and ultimate tensile strengths, and the brittle fracture behavior. The alloy can be a potential alternative of the conventional orthopedic implant materials in orthopedic applications.
