Titanium Round Disc
The Production Process Of Titanium Round Disc
The production of titanium round disc involves multi-step precision machining and technological innovation, and the core processes include melting, forging, heat treatment and quality control:
1. Melting Technology
Raw Material Selection And Pretreatment: high-purity titanium or titanium alloy (such as TC11, TA24, etc.) is used to ensure purity through crushing and screening.
Advanced Melting Methods: Vacuum self-consumable arc melting (VAR) and electron beam cooled bed melting (EBCHM) are widely used to reduce impurity content and improve material density. For example, TA24 titanium ingots are subjected to three vacuum self-consumption melts to ensure a homogeneous composition.
2. Forging Process
Multi-fire Upsetting Deformation: through multiple upsetting and lengthening, combined with temperature control, the grain is refined. For example, TC11 alloy needs to be upset for multiple rounds at 40-60°C below the phase change point, and the deformation is controlled at 30%-50% to eliminate microstructure inhomogeneity.
Two-phase Zone Forging: TA24 titanium alloy is forged in α+β two-phase zone to optimize the distribution of primary α phases and improve mechanical properties. The forging temperature is usually 900-1100°C, and the total forging ratio is greater than 30 to ensure uniform structure.
3. Heat Treatment And Surface Treatment
Precise Temperature-Controlled Annealing: The heat treatment temperature directly affects the microstructure. For example, when TA24 alloy is annealed at 700-900 °C, the α phase gradually dissolves into the β matrix, and the tensile strength decreases with increasing temperature, but the impact toughness increases.
Surface Finishing: Grinding, spraying, or coating to improve surface finish and corrosion resistance to meet biocompatibility requirements in medical devices and other fields.
4. Quality Control And Testing
Chemical Composition Analysis: spectroscopy and mass spectrometry to detect element content.
Mechanical Property Test: tensile and impact tests to evaluate strength and toughness.
Non-Destructive Testing: ultrasonic, X-ray inspection of internal defects.
The Application Field Of Titanium Round Disc
With its lightweight, high strength, corrosion resistance and other characteristics, titanium round cakes are widely used in the following fields:

Lightweight advantages: reduce the weight of the fuselage, reduce fuel consumption, and improve flight efficiency.
2. Medical Devices
Implants and surgical instruments: artificial joints, dental implants, etc., rely on the biocompatibility of titanium cakes; Surgical instruments take advantage of their corrosion resistance to extend their lifespan.
Surface modification technology: Enhance the anti-infection ability through coatings and expand the application of orthopedic restoration.
3. New Energy And Automotive Industry
New energy vehicle parts: lightweight chassis, battery structural parts, reduce body quality to improve mileage.
