Experimental Analysis of Superplastic Deformation of Titanium Alloy Based on Sports Equipment

Abstract

At present, titanium alloy is widely used in the field of materials. Because of its high specific strength and good corrosion resistance, it is also widely used in sports equipment. To overcome the shortcomings of traditional sports equipment, such as low yield and weak strength, the superplastic deformation effect of titanium alloy was tested and analyzed in this paper. The superplastic strength of titanium alloy was adjusted by adjusting the structure of the material. In this paper, by adjusting the proportion of Ti, Mo, alloy, CD, and Fe, the inductively coupled parameters of sports equipment were improved by vacuum consumable melting. The macro high temperature tensile test of sports equipment was carried out, and the temperature and strain rate under different states were recorded. Finally, the mechanism of superplastic deformation of titanium alloy for sports equipment is analyzed. The results show that the superplastic titanium alloy has higher elongation after fracture at high temperature and lower strain rate. The elongation ratio is more than 90% between 500 °C and 800 °C. At high temperature, the corrosion resistance of titanium alloy is high α, The number of phases decreases, and the alloy particles change from short rod to equiaxed. When the strain rate is reduced, the mechanical properties of titanium alloy are improved α, phase increases, the β the number of phases decreased. From its mechanism, the elongation of titanium alloy is caused by the dislocation movement caused by its structure. Therefore, titanium alloy in sports equipment can generally increase the short axis shape to improve the superplasticity of titanium alloy.
