What a coincidence...

TUSAŞ Engine Industries Inc:

"We have successfully developed the superplastic forming process—a hot forming method for titanium alloys, which are preferred in aerospace applications due to their high performance under demanding conditions—and made it available to our country’s aerospace industry. Through the DİLEK project, we have enabled the manufacture of large and complex titanium alloy components—intended for use in aircraft fuselages and engines—in a single operation under conditions specific to our country"

This question is indeed somewhat difficult to understand. To put it simply, the strength of titanium alloy alone is far from sufficient to meet the technical requirements.

Thousands of years ago, humans learned forging techniques. It uses hammering to eliminate internal imperfections in metal, altering its crystal structure and thus increasing its strength.

In modern industry, an upgraded version of this process, "die forging," is frequently used to manufacture special load-bearing structural components. However, this process is mainly used for small parts and steel components, with pressures primarily in the thousands of tons range.

When developing the F-22 fighter jet, the Americans independently developed a super-heavy, one-piece die forging machine, pioneering the use of large-scale die forging technology to manufacture the F-22's titanium alloy mid-frame. It precisely applies tens of thousands of tons of pressure to the titanium alloy workpiece, forming a high-strength structural component.

The Soviet Union/Russia also had super-heavy die forging machines. However, their precision machining capabilities were insufficient, resulting in workpieces manufactured by these machines failing to meet the required precision and internal mechanical balance. Therefore, Russia can only adopt a modular structure. ------ France once purchased one of these heavy machines from the Soviet Union.

In the early stages of the J-20 fighter jet development, China lacked a super-heavy, one-piece forging machine and had to resort to a splicing process. In 2013, China National Erzhong Group successfully developed an 80,000-ton super-heavy, one-piece forging machine. After numerous trials and adjustments, the machine began mass production of these titanium alloy mid-frames.

==================================

The core of this process is not molding, but rather altering the internal structure of the material through pressure of tens of thousands of tons. This shape can certainly be manufactured using 3D titanium alloy printing or other molding technologies. However, the structural strength of their workpieces is not even in the same league.

Tesla pioneered this technology in automotive manufacturing (6,000-ton level) when producing the Model Y. Later, in the production of the Cybertruck, they increased the pressure to the 9,000-ton level. Some Chinese companies followed suit, currently achieving pressures of 10,000-16,000 tons.

These machines used in car manufacturing can only use aluminum alloys, and the pressure requirements are vastly different from those for fighter jets. Even so, a single civilian-grade integrated die-casting machine costs around 100 million yuan. The cost of a military-grade ultra-heavy integrated die-casting machine ranges from hundreds of millions to billions of US dollars.

Large scale die forging for the F-22 Raptor relies on the Heavy Press Program, which utilizes massive, multi story hydraulic presses to form high strength structural components. By forcing heated titanium billets into precise closed dies under extreme tonnage, manufacturers create massive, lightweight, and incredibly durable parts that define the stealth fighter's airframe

YES.

I don't speak English. I use Chinese terminology and then translate it into English using translation software. There may be many issues with the terminology involved.
