Into the world of titanium forgings: from design to production

Titanium alloy forgings are high performance materials widely used in aviation, aerospace, medical and other fields. From design to production, the production process of titanium alloy forgings is very complex and demanding. Here are the steps to enter the world of titanium forgings.

First, the design phase

The design of titanium alloy forgings needs to consider several factors.

First of all, you need to choose the right titanium alloy. Different application scenarios require titanium alloys with different compositions and characteristics. For example, in the field of aviation, commonly used titanium alloys are Ti-6Al-4V, Ti-5Al-2.5Fe, etc., which have high strength and corrosion resistance.

Secondly, the structural design of forgings needs to be carried out according to the application scenarios and requirements. This includes determining the shape, size, thickness, etc. of the forgings, while taking into account the processability and economy of the forgings.

Finally, it is necessary to formulate a reasonable process route. This includes choosing the right processing method, determining the heating and holding time, and selecting the right equipment and tools.

Second, the production stage

The production of titanium alloy forgings requires several steps.

First of all, it is necessary to select high-purity, high-quality titanium alloy materials, and cut and surface treatment.

Secondly, it needs to be preheated. The deformation resistance of titanium alloy is large, and it needs to be heated to a certain temperature to be forged. Preheating treatment can reduce forging difficulty and improve forging efficiency.

Next comes the forging process. Forging needs to be carried out under high pressure or impact force to deform the titanium alloy and fill the mold shape. In the forging process, it is necessary to pay attention to controlling factors such as temperature, pressure and time to avoid defects such as cracks.

Finally, heat treatment is required. Heat treatment can improve the strength and corrosion resistance of titanium alloys, while removing residual stress. In the heat treatment process, it is necessary to pay attention to controlling factors such as heating speed, holding time and cooling speed to ensure that the microstructure and mechanical properties of titanium alloy meet the requirements.

In addition, the method of flame cutting can be used for the parts that are difficult to shape and difficult to access, such as gears. For the finishing of large thin-walled structural parts, EDM wire cutting is often used. Edm wire cutting has the advantage of high efficiency (up to more than 90%) and is not limited by the material being processed. According to the surface roughness of the product requirements, choose the corresponding grinding wheel, commonly used diamond grinding wheel and cubic borax nitride wheel, the former is suitable for roughing, the latter is suitable for finishing.
