Firstly, optimizing material selection is the foundation for reducing the processing difficulty of titanium alloy sheet metal. There are many types of titanium alloys with significant differences in properties. In practical applications, it is necessary to select titanium alloy grades with good forming properties according to the specific use environment and performance requirements of the parts, such as TC4, TA1, etc. In addition, adjusting the alloy composition or using new titanium alloy materials (such as beta titanium alloys) can significantly improve the plasticity and forming properties of the material.

　　Secondly, reasonably designing process parameters is one of the key measures. Titanium alloy has a low thermal conductivity, which is prone to local high temperatures during the processing process, leading to degradation of material properties. Therefore, using warm forming or hot forming processes can effectively improve the ductility and processability of the material. At the same time, controlling appropriate forming speed, temperature, and lubrication conditions helps to reduce friction and stress concentration, avoiding the occurrence of cracks.



Thirdly, improving the forming process is also an important means to reduce the processing difficulty. Traditional stamping forming is relatively difficult for titanium alloy, while the use of advanced processes such as superplastic forming, hydraulic forming, and laser-assisted forming can significantly enhance the forming ability of titanium alloy sheet metal. For example, hydraulic forming achieves uniform loading through liquid pressure, reducing local stress concentration, which is conducive to the processing of complex-shaped parts; laser-assisted heating can improve the plasticity of the material locally, thereby improving the forming performance.



In addition, strengthening mold design and surface treatment should not be ignored either. The geometric shape, surface roughness, and material selection of the mold will affect the flow and friction state of titanium alloy sheet metal. The use of high-wear-resistant, low-friction coefficient mold materials, and polishing or coating treatment of the mold surface, such as PVD coating, can effectively reduce friction and improve the forming quality.



Finally, strengthening process simulation and data analysis is an indispensable link in modern manufacturing. Through finite element simulation technology, it is possible to predict in advance the distribution of stress and strain during the forming process, optimize process parameters, reduce trial-and-error costs, and improve the success rate of one-time forming.

　　In summary, although titanium alloy sheet metal processing presents certain technical challenges, it is completely possible to effectively reduce its processing difficulty through various measures such as reasonable material selection, optimization of process parameters, improvement of forming methods, enhancement of mold quality, and strengthening of digital simulation, thereby promoting the wider application of titanium alloy in the field of high-end manufacturing.
