Due to the high manufacturing cost of titanium alloys, in order to reduce costs, the competitiveness of titanium alloys in the entire metal material market has increased at a lower price. It is generally believed that titanium has unparalleled superior performance compared to other materials, but the price of titanium often prohibits consumers (especially car manufacturers). The emergence of high-quality, low-cost titanium alloys will certainly contribute to the promotion and application of titanium and titanium alloys.
From the perspective of domestic and international application status and 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, to develop alloys with higher service temperature, higher specific strength, higher specific modulus, better corrosion resistance and wear resistance.
2) Multi-function, that is, the development of titanium alloys with various special functions and uses, such as high damping, low expansion, constant resistance, high resistance, electrolytic passivation and hydrogen storage, shape memory, superconductivity, low modulus biomedical And other titanium alloys to further expand the application of titanium and titanium alloys.
3) Deepen the research of traditional alloys, improve the practical performance of existing alloys, and expand the application range of traditional alloys through the improvement of equipment and processes.
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 that contain no or almost no precious metal elements, and add inexpensive elements such as iron, oxygen, and nitrogen to develop titanium alloys that are easy to process and shape, easy to cut, and alloy elements and master alloys are cheap. Develop titanium alloys and use prohibited materials to improve the recovery and utilization of prohibited titanium. This is particularly important for reducing the cost of civilian titanium alloys.
6) Use advanced computer technology to simulate the deformation and processing of the workpiece, predict the evolution of the metal microstructure, and even predict the mechanical properties of the product (yield strength, tensile strength, elongation, hardness, etc.). ), and design or improve moulds and tooling; analyze and process test results, reduce test volume, improve work efficiency, and reduce development costs.
