Heating forming technology of titanium alloy

I. Introduction

Titanium alloy has good mechanical properties, chemical stability and corrosion resistance, so it is widely used in aerospace, medical, energy conservation and environmental protection and other fields. Titanium alloys are difficult to process, and some alloys cannot even be processed into complex parts through conventional processing methods. Therefore, titanium alloy heating forming technology is widely used in the preparation of titanium alloy parts.

2. Reasons for heating and forming of titanium alloys

Titanium alloys are more difficult to process than traditional aluminum alloys, steels and other materials. The main reasons are that titanium alloys have complex composition, severe work hardening, and poor high-temperature oxidation resistance. Heating forming is a commonly used processing method that can make up for the difficulty of processing titanium alloys.

The principle of thermoforming is to heat titanium alloy parts to make them plastic, and then use pressure to shape them. Therefore, heating forming can effectively reduce the processing difficulty of titanium alloys, while also ensuring the overall performance of titanium alloy parts such as strength and corrosion resistance.

3. Methods of heating and forming titanium alloys

⑴. Hot rolling forming

Hot roll forming is performed by heating titanium alloy to its plastic zone, and then using hot rollers to process it to form the desired shape. Hot rolling can play an important role in reducing stress, improving structure and increasing the strength of titanium alloys.

⑵ Hot extrusion forming

Hot extrusion is formed by heating titanium alloy to its plastic zone and then forming it into the desired shape by extrusion. Hot extrusion has the advantages of high efficiency and high quality, and is suitable for producing large quantities of high-precision titanium alloy parts.

⑶Hot forging

Hot forging is achieved by heating titanium alloy to its plastic zone and then using pressure to form it to obtain the desired shape. Hot forging can improve the strength and hardness of titanium alloys and greatly reduce costs while maintaining high forming accuracy.

4. Application of titanium alloy heating forming technology

Titanium alloy heating forming technology is widely used in aerospace, medical, energy and other fields. In the aerospace field, heating forming can prepare complex parts such as engine blades, guide blades, etc. In the medical field, heating forming can prepare artificial joints, dental implants, etc. In the energy field, heat forming can prepare efficient energy conversion devices

5. Conclusion

Titanium alloy heating forming technology is one of the important steps in preparing titanium alloy parts. Heating forming can effectively make up for the shortcomings of high processing difficulty of titanium alloy and ensure the comprehensive performance of titanium alloy parts such as strength and corrosion resistance. Titanium alloy heating forming technology is widely used in aerospace, medical, energy and other fields, and has important application prospects.
