1. Material Features and Technical Advantages of TB13 Titanium Alloy Rod
1.1 Unique alloy composition and internal microstructure
Engineers carefully design the chemical makeup of TB13 titanium alloy rod. Titanium acts as the base metal. Aluminum content stays between 3.0% and 4.5%. Vanadium content ranges from 20.0% to 23.0%. Manufacturers set strict limits for impurity elements: Fe ≤ 0.20%, C ≤ 0.10%, N ≤ 0.05%, H ≤ 0.015%, O ≤ 0.20%. This specific element ratio creates a metastable beta phase structure. The structure brings balanced excellent material properties. Compared with traditional alpha+beta titanium alloys, the beta phase structure of TB13 delivers lower elastic modulus (roughly 60–70 GPa) and stronger cold forming capacity. The material takes cold deformation up to 80% without cracks.
1.2 Excellent mechanical performance
TB13 titanium alloy rod shows great ductility under beta phase stabilized condition. Elongation reaches 20%–30%. This property simplifies forming work for complex parts. Beta solution treatment plus aging heat treatment lifts material strength sharply. Tensile strength hits 900–1100 MPa, yield strength reaches 800–1000 MPa, while the material keeps good toughness. This balance between strength and toughness makes TB13 the top choice for structural parts under heavy stress. Its fatigue performance stands out among alloy materials. The material resists fatigue crack expansion steadily under cyclic loads. It fits products that bear alternating stress for long service periods.
1.3 High elasticity and stable shape retention
One core feature of TB13 titanium alloy rod is its superior elastic performance. The material handles large elastic deformation (elastic limit strain reaches 2%–3%) with no permanent distortion. It bounces back to its original shape after bending. This high elasticity comes from the metastable beta phase’s low shear modulus and fully reversible crystal lattice. For eyewear frame production, this feature means frames recover fully after accidental squeeze or twist. It greatly cuts product deformation damage and after-sales repair costs.

3. Production Process and Quality Control of TB13 Titanium Alloy Rod
3.1 Advanced melting and forging technology
Production of TB13 titanium alloy rod starts with careful selection of high-purity raw materials and electrode fabrication. Factories adopt Vacuum Arc Remelting (VAR) technology. Multiple remelting cycles under high vacuum fully remove impurity elements and gaseous inclusions. The process secures uniform alloy composition and high metal purity. The forging stage uses multi-directional forging techniques. This process breaks down as-cast microstructure, refines grain size and eliminates element segregation. It builds a high-quality foundation for all subsequent forming steps.
3.2 Precision rolling and cold working process
Forged rod blanks pass through hot rolling and cold drawing steps to form finished TB13 titanium alloy rod of all target sizes. Hot rolling controls forming temperature within beta phase region or alpha+beta dual-phase region. Production teams select suitable rolling temperatures and pass reduction rates based on target mechanical properties. Cold drawing acts as a core processing step for TB13 titanium alloy rod. The alloy’s excellent cold forming capacity supports multi-pass drawing with small single-pass deformation. This method delivers precise dimensions and mirror-smooth surfaces. Dislocation strengthening and work hardening generated during cold forming get adjusted via follow-up annealing steps. Operators gain precise control over the final mechanical properties of the rod.
3.3 Heat treatment and surface finishing process
Beta phase stabilization serves as the core process to adjust the performance of TB13 titanium alloy rod. The standard workflow holds the rod at 750–850°C for a set duration then conducts rapid cooling via water quenching or gas quenching. This cycle generates the target metastable beta phase microstructure. Aging treatment runs at 450–550°C. Precipitation of fine alpha phase particles brings significant strength gains. Computer-controlled vacuum heat treatment furnaces deliver precise temperature uniformity within ±5°C and full protective atmosphere coverage. The equipment prevents surface oxidation and external contamination. Surface finishing steps include pickling, polishing and precision grinding. These steps strip surface oxide layers and reach target surface roughness of Ra0.4–0.8 μm to meet appearance and performance standards of high-end applications.
