1、 Application Fields of TC4 Titanium Alloy Rod

1. Aerospace

Core components: engine fan blades, compressor discs, aircraft load-bearing structural components, etc., utilizing their high specific strength and high temperature resistance.

Advantages: Significant weight reduction effect, improved aircraft fuel efficiency and payload capacity.

2. Automotive industry

Key applications: Lightweight transmission shafts, connecting rods, exhaust systems, etc., improve fuel economy by reducing component weight.

Challenge: Optimize parameters during processing to address issues such as material sticking and thermal deformation.

3. Petrochemical and Shipbuilding

Corrosion resistant components: refinery reactor liners, ship propellers, seawater pipeline systems, resistant to strong acids and seawater corrosion.

2、 Processing technology

1. Material preparation

Annealing treatment: Before processing, it is necessary to anneal at 700-750 ℃ for 1-2 hours to reduce hardness and eliminate residual stress.

Surface cleaning: Remove oxide film and grease to prevent processing contamination.

2. Forming process

Forging: Temperature 950-1200 ℃, deformation 20-40%, improves density and mechanical properties.

Rolling: Hot rolled at 700-900 ℃, with a deformation of 50-70%, suitable for the production of plates/bars.

3. Cutting Processing

Tool selection: Hard alloy or ceramic tools, paired with high-speed cutting.

Cooling measures: Use specialized coolant and control the cutting temperature to ≤ 150 ℃ to avoid material overheating and softening.

4. Heat treatment and surface treatment

Time hardening: Keep at 520-550 ℃ for 2-4 hours to improve strength and fatigue life.

Surface modification: shot peening or anodizing.

5. Welding process

Recommended methods: TIG welding, plasma arc welding, vacuum electron beam welding, requiring full protection with inert gas.

3、 Processing precautions

1. Thermal sensitivity: Avoid excessively high processing temperatures to prevent grain coarsening and performance degradation.

2. Tool wear: Titanium alloy is prone to sticking to the tool, so it is necessary to regularly replace the tool and optimize the feed rate.

3. Environmental control: Keep the processing area dry to prevent hydrogen embrittlement.

Through the above process optimization, TC4 titanium alloy rods can fully leverage their advantages of lightweight, corrosion resistance, and high strength, meeting the needs of high-end industrial fields.
