How strong is titanium alloy

Tntroduce
Titanium is an important structural metal developed in the 1950s. Titanium alloys have high strength, good corrosion resistance, and high heat resistance...
The first practical titanium alloy was the Ti-6Al-4V alloy successfully developed in the United States in 1954. Due to its excellent heat resistance, strength, plasticity, toughness, formability, weldability, corrosion resistance and biocompatibility, It is better and has become the trump card alloy in the titanium alloy industry. The usage of this alloy accounts for 75% to 85% of all titanium alloys. Many other titanium alloys can be regarded as modifications of Ti-6Al-4V alloy.
What is titanium alloy
Titanium alloy refers to a variety of alloy metals made of titanium and other metals. It is an alloy composed of titanium as the base and other elements added. There are two types of isomorphic crystals of titanium: below 882°C, it is α-titanium with a close-packed hexagonal structure, and above 882°C, it is β-titanium with a body-centered cubic structure.
How strong is titanium alloy
Titanium alloy is not considered hard, it is just high in strength. It cannot even be said to be high in strength, it can only be said to be higher in strength. The hardness of titanium alloy is much lower than that of ordinary quenched steel (I also wanted to make a titanium alloy knife earlier). There are pits), it will be greatly improved after nitriding treatment, but it is still not as hard as silicon carbide, boron carbide and other high-hardness materials.
High strength
The density of titanium alloys is generally around 4.51g/cm3, which is only 60% 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 greater than that of other metal structural materials, and parts with high unit strength, good rigidity, and light weight can be produced. Titanium alloys are used in aircraft engine components, frames, skins, fasteners and landing gear.
High thermal intensity
The service temperature is several hundred degrees higher than that of aluminum alloys. It can still maintain the required strength at moderate temperatures and can work for a long time at temperatures of 450 to 500°C. These two types of titanium alloys still have high strength in the range of 150°C to 500°C. Specific strength, while the specific strength of aluminum alloy drops significantly at 150°C. The working temperature of titanium alloy can reach 500℃, while that of aluminum alloy is below 200℃.
Summarize
With the continuous advancement of science and technology, the application fields of titanium alloys will continue to expand. In aviation, aerospace, medical, energy and other fields, titanium alloys will continue to give full play to their advantages in light weight, strength, corrosion resistance and other groups, becoming the backbone of future advanced manufacturing and engineering technology.
Generally speaking, titanium alloys have restored lightness and strengthened bodies, as well as good understanding of various extreme environments, and are constantly leading the development direction of materials science. In the future, we have reason to expect that titanium alloys will definitely show their true strength in more fields and promote continuous exploration, innovation and progress of mankind.
