Prospect of Processing and Manufacturing Technology for Titanium and Titanium Alloys


Because the cost of titanium alloy manufacturing is very high, in order to make it cost-effective, the competitiveness of titanium alloy in the whole metal material market will be increased at a lower price. It is generally believed that titanium has incomparable superior properties compared with other materials, but the price of titanium often deters consumers (especially automobile manufacturers). The appearance of high-quality and low-cost titanium alloys will certainly help to expand the application of titanium and titanium alloys.

From the 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 means the development of alloys with higher temperature, higher specific strength, higher specific modulus, better corrosion resistance and wear resistance.

(2) Multifunction means the development of titanium alloys with special functions and applications, 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, in order to further expand the application of titanium and titanium alloys.

(3) Deepening the research of traditional alloys, improving the practical properties of existing alloys and expanding the application scope of traditional alloys through equipment and process improvement.

(4) Adopting advanced processing technology, large-scale and continuous processing equipment, developing continuous processing technology, direct rolling technology, cold forming technology and near net forming technology, in order to improve the production efficiency, product yield and product performance of titanium alloy.

(5) Developing alloys without or without precious metal elements, adding cheap elements such as iron, oxygen and nitrogen, and developing low-cost titanium alloys that are easy to process, easy to cut, alloy elements and parent alloys. To develop titanium alloys to maximize the use of waste materials and improve the recovery and utilization rate of waste titanium. This is particularly important for reducing the cost of civil titanium alloys.

(6) Using advanced computer technology to simulate the deformation process of workpiece, predict the evolution of metal micro-structure, and even predict the mechanical properties of final products (yield strength, tensile strength, elongation and hardness), design or improve dies and tooling; analyze and process test results, reduce test load, improve work efficiency and reduce. Development cost.
