A variety of α + β type titanium alloys have been developed that hold promise for orthopedic implants, including Ti-6Al-4V, Ti-6Al-7Nb, Ti-5Al-2.5Fe, and the like. However, the titanium alloy has a Young's modulus (about 10-40 GPa) which is obviously higher than that of human bone, and is not matched with that of human bone, so that a stress shielding effect can occur after the titanium alloy is implanted, and the body function is failed. Some alloys contain toxic elements such as Al and V, which can cause harm to human health. The development of new titanium alloys with low young's modulus and good biocompatibility has been a hotspot in this field.
The Ti2448(Ti-24Nb-4Zr-Sn, wt%) alloy is a beta type titanium alloy with low Young's modulus and good biocompatibility developed in recent years. However, the Young's modulus of the existing Ti2448 alloy is 43GPa at the lowest, and is still slightly higher than that of human bone. Therefore, the invention optimizes the preparation process based on the Ti2448 alloy, further reduces the Young modulus of the alloy to 33GPa by adding proper pre-strain without damaging the tensile strength of the alloy, and ensures that the ratio of the strength to the modulus of the alloy has certain advantages.

(1) preparing materials: four simple metal substances of Ti, Nb, Zr and Sn with the purity of 99.99 percent are taken as raw materials, and the weight percentage of Ti: 64 wt.%, Nb: 24 wt.%, Zr: 4 wt.%, Sn: 8 wt.% of the raw materials;
(2) smelting: preparing an ingot casting alloy: and (2) smelting the metal simple substance mixed in the step (1) in vacuum arc smelting, and turning for 6-7 times during smelting to ensure the uniformity of alloy ingot components.
(3) Testing of as-cast alloy: and (5) characterizing the microstructure and the compression mechanical property of the as-cast alloy. The results of FIG. 1 were obtained.
(4) Rolling: firstly, carrying out a second rolling process parameter on the alloy, namely carrying out hot rolling on the alloy at 850 ℃, carrying out hot rolling on the alloy by keeping the temperature of the alloy at 850 ℃ for 30Min, and then returning the alloy to the furnace and keeping the temperature for 5-10Min before each pass of hot rolling in order to prevent the alloy from cracking, wherein the thickness of a finally obtained plate sample is 1.5 mm.
(5) Solution treatment: cutting the hot-rolled plate-shaped sample according to the required size, carrying out solution treatment on the cut sample, heating the alloy to 850 ℃ along with the furnace at room temperature, wherein the heating rate is 5K/Min, keeping the temperature at 850 ℃ for 90Min, then taking out a sample, breaking a quartz tube, and carrying out water quenching.
(6) Solid solution alloy: the cyclic tensile property of the Ti2448 alloy is tested, and proper pre-strain is added to the alloy, so that the Young modulus of the alloy is further reduced.
As can be seen from the photographs of the as-cast Ti2448 alloy shown in FIG. 1, the as-cast Ti2448 alloy prepared in the above examples, as tested in step (3), had two phases of β + α ". Compared with the existing titanium alloy, the titanium alloy has better compression performance, the compressive strength reaches 1302MPa, the plasticity is about 35.3 percent, and the Young modulus of the alloy is only 49 GPa. As can be seen from the microstructure photo, the beta phase with clear grain boundaries can be observed under the low power of the as-cast Ti2448 alloy, the crystal grains are coarse and millimeter-sized and have irregular shapes, the beta subgrain grains of the parent phase with different sizes and shapes are distributed in the coarse crystal grains, and the micro-morphology of the alloy under the high power also shows that alpha' martensite with different orientations and sizes exists in the crystal grains. These structures make it easier to obtain alloys with relatively low young's modulus and also good strength and elongation. Hot rolling at 850 ℃ and solution treatment at 850 ℃ are carried out on the as-cast alloy in the steps (4) and (5), the obtained solution alloy is subjected to cyclic stretching, and appropriate pre-strain is added. As shown in fig. 2, the young's modulus of the alloy varied with the pre-strain addition, and it was found that at cycle 5, strain 2.5%, the lowest young's modulus was obtained, with the young's modulus tending to decrease and then increase. Then, 2% and 3% of prestrain were added to the alloy, respectively, and it was found that the young's modulus of the alloy achieved a further lowering effect after the 2% prestrain was added. Thus, the addition of a suitable pre-strain, i.e. a strain of 2%, as proposed herein, can reduce the young's modulus to 33 GPa. FIG. 3 also shows a comparison of the strength to modulus ratio of the prior art alloy and the alloy made herein, which was found to have certain advantages.

As shown in fig. 4.
