Characteristics of Titanium Alloy Tubes
Titanium alloy tube performance: As a cutting-edge material, titanium alloy tubes depend on the purity and impurity levels of elements like carbon, nitrogen, hydrogen, and oxygen. The purest form, titanium iodide, contains impurities of less than 0.1%, offering low strength but high plasticity. Industrial pure titanium (99.5%) showcases the following properties: density ρ=4.5g/ cubic cm, melting point 1725ºC, thermal conductivity λ=15.24W/(m.K), tensile strength σb=539MPa, elongation δ=25%, section shrinkage ψ=25%, elastic modulus E=1.078×105MPa, and hardness HB195.
Distinct Advantages of Titanium Alloy
Titanium alloy stands out with several distinct advantages over other metals:
Higher strength-to-density ratio: With tensile strength reaching between 100 to 140kgf/mm² and a density that's only 60% of steel, titanium alloy offers an impressive strength-to-weight benefit.
Excellent medium temperature strength: Capable of maintaining necessary strength at temperatures several hundred degrees higher than aluminum alloys, titanium alloys can consistently perform at 450~500°C.
Outstanding corrosion resistance: Titanium quickly forms a uniform, dense oxide film in the atmosphere, protecting it against various erosive media. It excels in oxidizing and neutral conditions, particularly in seawater, wet chlorine gas, and chloride solutions. However, its resistance diminishes in reducing environments like hydrochloric acid.
Superior low-temperature performance: Certain titanium alloys, such as TA7, retain notable plasticity even at extreme low temperatures of -253°C.
Low elastic modulus, minimal thermal conductivity, and non-ferromagnetic properties.
High hardness.
While titanium alloys have poor cold stamping properties, they exhibit excellent thermoplasticity.
By adjusting the heat treatment process, various phase compositions and microstructures can be tailored in titanium alloys. Generally, fine equiaxial structures provide superior plasticity, thermal stability, and fatigue strength, whereas acicular structures offer high prolonged strength, creep resistance, and fracture toughness. A balanced mix of equiaxed and acicular structures yields well-rounded properties.
Common heat treatment methods for titanium alloys include annealing, solution treatment, and aging treatment. Annealing is employed to eliminate internal stress, enhance plasticity, and stabilize the structure, achieving superior comprehensive properties. Typically, the annealing temperature for α alloy and (α+β) alloy is set at 120 ~ 200ºC below the (α+β) → β phase transition point. In contrast, solution and aging treatment involve rapid cooling from high temperatures to form martensitic α' phase and metastable β phase, followed by heat preservation in the middle temperature region to decompose these phases into α phase or other small dispersed second phase particles, thereby strengthening the alloy. Generally, (α+β) alloy is quenched at 40 ~ 100ºC below the α+β → β phase transition point, while metastable β alloy is quenched at 40 ~ 80ºC above this point. The aging treatment temperature usually ranges from 450 ~ 550ºC. Additionally, to meet specific workpiece requirements, the industry employs double annealing, isothermal annealing, β heat treatment, deformation heat treatment, and other sophisticated metal heat treatment processes.

Titanium alloy is predominantly utilized in manufacturing aircraft engine compressor components, with further applications in rockets, missiles, and high-speed aircraft structural parts. By the mid-1960s, titanium and its alloys extended into general industry, crucial for producing electrodes for the electrolytic industry, power station condensers, oil refining and seawater desalination heaters, and devices for controlling environmental pollution. Recognized as corrosion-resistant structural materials, these alloys are also used to create hydrogen storage materials and shape memory alloys.
China embarked on titanium and titanium alloy research in 1956, leading to the commencement of industrial production of titanium materials and the development of the TB2 alloy by the mid-1960s.
