Development characteristics of processing technology for titanium alloy materials and products
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 been increased at lower prices. People generally believe that titanium has unparalleled superior performance compared to other materials, but the price of titanium often discourages consumers, especially car manufacturers. The emergence of high-quality and low-cost titanium alloys will undoubtedly contribute to the promotion and 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 refers to the development of alloys with higher operating temperatures, higher specific strength, higher specific modulus, better corrosion resistance, and wear resistance.
2) Multifunctional refers to the development of titanium alloys with various special functions and applications, such as high damping, low expansion, constant resistance, high resistance, resistance to electrolytic passivation and hydrogen storage, shape memory, superconductivity, low modulus biomedical applications, etc., further expanding the applications 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 equipment and process improvements.
4) By adopting advanced processing technology and large-scale continuous processing equipment, we have developed continuous processing technology, direct rolling technology, cold forming technology, and near net forming technology to improve the production efficiency, yield, and product performance of titanium alloys.
5) Reduce costs, develop alloys that do not contain or almost do not contain precious metal elements, and add inexpensive elements such as iron, oxygen, and nitrogen. Develop titanium alloys that are easy to process and shape, easy to cut, and have inexpensive alloying elements and parent alloys. Develop titanium alloys, utilize prohibited materials, and improve the recovery and utilization rate of prohibited titanium. This is particularly important for reducing the cost of civilian titanium alloys.
6) Using advanced computer technology to simulate the deformation and processing of workpieces, predict the evolution of metal microstructure, and predict the mechanical properties of products (yield strength, tensile strength, elongation, hardness, etc.). And design or improve molds and fixtures; Analyze and process test results, reduce testing volume, improve work efficiency, and lower development costs.
