Due to the high manufacturing cost of titanium alloys, the competitiveness of titanium alloys in the entire metal material market has been improved at a lower price to reduce costs. It is generally believed that titanium has incomparable superior performance compared with other materials, but the price of titanium often makes consumers (especially automakers). The emergence of high-quality, low-cost titanium alloys will help promote the application of titanium and titanium alloys.
From the current application status at home and abroad and the development of titanium processing technology, the plastic processing technology of titanium and titanium alloys will develop in the following directions in the future:
1) High performance, that is, the development of alloys with higher operating temperature, higher specific strength, higher specific modulus, better corrosion resistance, and wear resistance.
2) Multifunctional, that is, the development of titanium alloys with various special functions and uses, such as high damping, low expansion, constant resistance, high resistance, anti-electrolytic passivation and hydrogen storage, shape memory, superconducting, low modulus biomedical and other titanium alloys, to further expand the application of titanium and titanium alloys.
3) Deepen the research on traditional alloys, improve the practical performance of existing alloys, and expand the application range of traditional alloys by improving equipment and processes.
4) Adopt advanced processing technology and large-scale continuous processing equipment, develop continuous processing technology, direct rolling technology, cold forming technology, and near-net forming technology, and improve the production efficiency, yield rate, and product performance of titanium alloys.
5) Reduce costs, develop alloys that contain no or almost no precious metal elements, and add cheap elements such as iron, oxygen, and nitrogen to develop titanium alloys that are easy to process and form, easy to cut, and cheap in alloying elements and master alloys. Develop titanium alloys, use banned materials, and improve the recovery rate and utilization rate of banned titanium. This is particularly important for reducing the cost of civilian titanium alloys.
6) Use advanced computer technology to simulate the deformation and processing process of workpieces, predict the evolution of metal microstructures, and even predict the mechanical properties of products (yield strength, tensile strength, elongation, hardness, etc.). design or improve molds and tooling; analyze and process test results, reduce the amount of testing, improve work efficiency, and reduce development costs.
