Titanium alloy refers to various alloy metals made by combining titanium with other metals. Titanium is an important structural metal developed in the 1950s, known for its high strength, excellent corrosion resistance, and high heat resistance. During the 1950s to 1960s, the focus was primarily on developing high-temperature titanium alloys for aircraft engines and structural titanium alloys for airframes.
Titanium is a novel metal, and its properties are related to the content of impurities such as carbon, nitrogen, hydrogen, and oxygen. The purest iodized titanium has an impurity content of no more than 0.1%, but it exhibits low strength and high plasticity. The properties of 99.5% industrial pure titanium are as follows: density ρ = 4.5 g/cm³, melting point = 1725°C, thermal conductivity λ = 15.24 W/(m·K), tensile strength σb = 539 MPa, elongation δ = 25%, reduction of area ψ = 25%, elastic modulus E = 1.078 × 10⁵ MPa, and hardness HB195.
High Strength
The density of titanium alloy is generally around 4.51 g/cm³, only 60% that of steel. Some high-strength titanium alloys exceed the strength of many alloy structural steels. Therefore, the specific strength (strength/density) of titanium alloy is much higher than that of other metal structural materials, enabling the production of components with high unit strength, good rigidity, and light weight. Titanium alloy is used in aircraft engine components, frames, skins, fasteners, and landing gear.
High Thermal Strength
Titanium alloy can operate at temperatures several hundred degrees higher than aluminum alloys and maintains the required strength at moderate temperatures. It can work for extended periods at 450–500°C. These two types of titanium alloys still exhibit high specific strength in the range of 150°C to 500°C, while the specific strength of aluminum alloys significantly decreases at 150°C. Titanium alloy can operate at temperatures up to 500°C, whereas aluminum alloys are limited to below 200°C.
Excellent Corrosion Resistance
Titanium alloy performs far better than stainless steel in corrosive environments such as humid atmospheres and seawater. It exhibits strong resistance to pitting, acid erosion, and stress corrosion. It also has excellent corrosion resistance to alkalis, chlorides, chlorine-containing organic substances, nitric acid, sulfuric acid, etc. However, titanium has poor corrosion resistance in reducing oxygen and chromate media.
Good Low-Temperature Performance
Titanium alloy retains its mechanical properties at low and ultra-low temperatures. Titanium alloys with very low interstitial elements, such as TA7, maintain certain plasticity even at -253°C. Thus, titanium alloy is also an important low-temperature structural material.
High Chemical Reactivity
Titanium is highly chemically reactive and undergoes strong chemical reactions with O₂, N₂, H₂, CO, CO₂, water vapor, ammonia, etc., in the atmosphere. When the carbon content exceeds 0.2%, hard TiC forms in the titanium alloy. At higher temperatures, interaction with nitrogen also forms a hard TiN surface layer. Above 600°C, titanium absorbs oxygen to form a highly hardened layer. Increasing hydrogen content also leads to the formation of an embrittled layer. The depth of the hard and brittle surface layer caused by gas absorption can reach 0.1–0.15 mm, with a hardening degree of 20%–30%. Titanium also has high chemical affinity, making it prone to adhesion on friction surfaces.
Low Thermal Conductivity and Elasticity
The thermal conductivity of titanium, λ = 15.24 W/(m·K), is about 1/4 that of nickel, 1/5 that of iron, and 1/14 that of aluminum. The thermal conductivity of various titanium alloys is approximately 50% lower than that of pure titanium. The elastic modulus of titanium alloy is about half that of steel, resulting in poor rigidity and susceptibility to deformation. It is not suitable for manufacturing slender rods and thin-walled components. During machining, the rebound on the processed surface is significant, about 2–3 times that of stainless steel, causing severe friction, adhesion, and adhesive wear on the tool's flank face.
