1. Reasonable selection of processing temperature

The deformation resistance of titanium flange is very sensitive to the deformation temperature. In order to reduce the deformation resistance, it is usually necessary to heat the metal to the β phase region above the phase transformation point to perform so-called β processing. This processing method can significantly improve the plasticity and toughness of the material, thereby reducing the deformation resistance. However, too high temperature will cause β grains to grow rapidly, form a coarse structure, and reduce the mechanical properties of the material. Therefore, the processing temperature needs to be selected reasonably, usually between 800-950°C.

2. Control the deformation rate

An increase in deformation rate will also lead to an increase in deformation resistance. Therefore, the deformation rate needs to be controlled during processing to avoid too fast deformation speed. Control of the deformation rate can be achieved by adjusting the speed and pressure of the forging equipment. In addition, the step-by-step forging method can also be used to gradually increase the amount of deformation to reduce the deformation resistance.

3. Optimize the forging process

The forging process has an important influence on the deformation resistance of titanium flange. In order to reduce the deformation resistance, multi-directional forging can be used to make the material uniformly stressed in multiple directions, thereby reducing local stress concentration. In addition, isothermal forging can also be used to maintain a constant temperature of the material throughout the processing process, thereby reducing deformation resistance.

4. Use appropriate lubricant

During the forging process, the use of appropriate lubricants can effectively reduce friction and thus reduce deformation resistance. Commonly used lubricants include graphite, molybdenum disulfide and oil-based lubricants. Choosing the right lubricant can not only reduce deformation resistance, but also extend the service life of the mold and improve processing efficiency.

5. Reasonably design the mold

The design of the mold also has an important impact on the deformation resistance of the titanium flange. Reasonable mold design can effectively disperse the stress of the material, thereby reducing the deformation resistance. For example, rounded corner design and smooth transition methods can be used to reduce the resistance of the mold to the material. In addition, the adjustable mold method can also be used to adjust the shape and size of the mold in real time according to the actual situation during the processing to reduce the deformation resistance.

In summary, through reasonable selection of processing temperature, control of deformation rate, optimization of forging process, use of appropriate lubricants and reasonable design of molds, the deformation resistance in titanium flange processing can be effectively controlled, thereby improving processing efficiency and product quality. .
