High-strength and high-plasticity Ti-Mo-Al-Zr-Nb beta titanium alloy with TWIP effect

The invention belongs to the technical field of titanium alloy materials, and discloses a high-strength and high-plasticity Ti-Mo-Al-Zr-Nb beta titanium alloy with a TWIP effect, which comprises Ti, Mo, Al, Zr and Nb, and comprises the following alloy components in percentage by weight: 13 to 15 percent of Mo, 0.9 to 1 percent of Al, 2.4 to 2.5 percent of Zr, 1.5 to 3.5 percent of Nb and the balance of Ti. According to the high-strength and high-plasticity Ti-Mo-Al-Zr-Nb beta titanium alloy, by adding various alloy elements such as Mo, Al, Zr and Nb, the solution strengthening effect is achieved, certain aging strengthening performance is achieved, and the strength of the high-strength and high-plasticity Ti-Mo-Al-Zr-Nb beta titanium alloy is improved. Alloy component design is carried out in combination with a cluster model, the research and development efficiency of a new material is effectively improved, the research and development cost is reduced, and the alloy has the twinning induced plasticity effect
