[0003] Titanium alloy forgings are a type of parts manufactured by forging process, made of titanium alloy material. Titanium alloy is a lightweight, high-strength, corrosion-resistant material widely used in aerospace, medical, automotive and other high-end applications.

[0004] In the existing cooling process of titanium alloy workpieces used in missile parts, coolant and air cooling are used.
