Due to the high cost of manufacturing titanium alloys, the competitiveness of titanium alloys in the overall metal materials market has increased at a lower price in order to reduce costs. It is widely recognized that titanium has unparalleled superior performance compared to other materials, but the price of titanium tends to discourage consumers (especially automobile manufacturers). The emergence of high-quality, low-cost titanium alloys will certainly help the popularization and application of titanium and Titanium Alloy processing.
From the current situation of domestic and foreign applications and the development of titanium alloy processing technology, titanium and titanium alloy plasticity processing technology will be developed in the following directions in the future.
1) high performance, that is, the development of alloys with higher service temperature, higher specific strength, higher specific modulus, better corrosion resistance and wear resistance.
2) multi-functional, that is, the development of titanium alloys with a variety of special functions and uses, such as high damping, low expansion, constant resistance, high resistance, anti-electrolytic passivation and hydrogen storage, shape memory, superconductivity, low-modulus biomedical 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 scope of traditional alloys through the improvement of equipment and process.
4)Adopt advanced processing technology, large-scale continuous processing equipment, develop continuous processing technology, direct rolling technology, cold forming technology and near-net forming technology to improve titanium alloy production efficiency, yield and product performance.
5) Reduce costs, develop alloys containing no or almost no precious metal elements, and add cheap elements such as iron, oxygen and nitrogen, and develop titanium alloys that are easy to process and form, easy to cut, and have cheap alloying elements and master alloys. Develop titanium alloys that utilize banned materials and increase the recycling rate and utilization of banned titanium. This is especially important to reduce the cost of civil titanium alloys.
6) Use advanced computer technology to simulate the deformation and processing of workpieces, to predict the evolution of the microstructure of the metal, and even to predict the mechanical properties of products (yield strength, tensile strength, elongation and hardness, etc.). , and design or improve molds and tooling; analyze and process test results to reduce the amount of testing, improve efficiency and reduce development costs.
