“…From a macroscopic point of view, the elastic modulus scale indicates the difficulty of the material elastic deformation under certain stress. The larger the elastic modulus, the more difficult the deformation [ 20 , 21 , 22 ]. From a perspective of the interaction force between atoms, the elastic modulus represents the strength of the interatomic bonding force.…”

The hot deformation behaviors of a new Ti-6Al-2Nb-2Zr-0.4B titanium alloy in the strain rate range 0.01–10.0 s−1 and temperature range 850–1060 °C were evaluated using hot compressing testing on a Gleeble-3800 simulator at 60% of deformation degree. The flow stress characteristics of the alloy were analyzed according to the true stress–strain curve. The constitutive equation was established to describe the change of deformation temperature and flow stress with strain rate. The thermal deformation activation energy Q was equal to 551.7 kJ/mol. The constitutive equation was ε ˙=e54.41[sinh (0.01σ)]2.35exp(−551.7/RT). On the basis of the dynamic material model and the instability criterion, the processing maps were established at the strain of 0.5. The experimental results revealed that in the (α + β) region deformation, the power dissipation rate reached 53% in the range of 0.01–0.05 s−1 and temperature range of 920–980 °C, and the deformation mechanism was dynamic recovery. In the β region deformation, the power dissipation rate reached 48% in the range of 0.01–0.1 s−1 and temperature range of 1010–1040 °C, and the deformation mechanism involved dynamic recovery and dynamic recrystallization.

“…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.

<p class="02abstracttext">Corrosion research of metal alloys of Zr-25Ti-5Sn and Zr-25Ti-3Sn-2Geas biomaterials has been carried out in fluid solution. Zr-25Ti-5Snalloy is a ternary metal alloy developed for hard tissue biomaterials. Zr-25Ti-5Sn and Zr-25Ti-3Sn-2Ge alloys is melted in electric arc furnace. After being melted Zr-25Ti-5Sn and Zr-25Ti-3Sn-2Ge were characterized by optical microscopy. Hardness testing was carried out by the hardness microvickers method to determine the effect of germanium addition on Zr-25Ti-5Sn alloys. Corrosion testing of ternary metal alloys Zr-25Ti-5Sn and Zr-25Ti-3Sn-2Ge was carried out by the Tafel polarization method using three electrode systems. From the results of microstructure examination with optical microscope, the microstructure found in the ternary metal alloy Zr-25Ti-5Sn and Zr-25Ti-3Sn-2Ge are parallel plates and dendritic. The hardness test results show that the addition of germanium to the Zr-25Ti-5Sn ternary alloy increased the hardness of the alloy. Corrosion test results on ternary alloy Zr-25Ti-5Sn and Zr-25Ti-3Sn-2Geindicated that corrosion resistance of Zr-25Ti-5Snincreased when no addition of Germanium to Zr-25Ti-5Snalloy.</p>
