What is TC4 (Ti6Al4V) Titanium Alloy Material
Now China has become a powerful country in science and technology, but do you know how powerful China's technology is? The manned space station alone is not enough, and now it has successfully broken through the key technology of nuclear fusion, even leading the world by 15 years. Does this mean that China is not far from the artificial sun? It turned out that the fully superconducting tokamak nuclear fusion experimental device developed by China at the Hefei Research Institute of the Chinese Academy of Sciences successfully achieved a record of 101 seconds of continuous operation at 120 million degrees Celsius, and broke the world record. Compared with the previous record in South Korea, China has time has been directly extended by 5 times, and it seems that we are one step closer to the practical stage of artificial sun.
The success of nuclear fusion technology will lead to the development of Ti6Al4V Powder.
What is TC4(Ti6Al4V)?
TC4(Ti6Al4V) alloy is a medium strength α-β type two-phase titanium alloy
containing 6% α-stabilizing element AI and 4% β-stabilizing element V. This
alloy has excellent comprehensive properties and has obtained the most extensive
applications in the aviation and aerospace industries. The long-term working
temperature of the alloy can reach 400 ℃. In the aviation industry, it is mainly
used to manufacture the fan and compressor disks and blades of the engine, as
well as the important load-bearing components such as beams, joints and
bulkheads in the aircraft structure.
The main semi-finished products of TC4 titanium alloy are bars, forgings,
thick plates, thin plates, profiles and wires, etc. The alloy is mainly used in
the annealed state, and can also be strengthened by solution aging treatment,
but the hardened cross section is generally not more than 25mm.
The alloy has good process plasticity and superplasticity, and is suitable
for various pressure forming. The alloy can also be welded and machined in
TC4(Ti6Al4V) heat treatment system
Plate: 700-850℃, 0.5-2h, air cooling; bar and forging: 700-800℃, 1-2h, air
2. Vacuum annealing
700-800°C, 0.5-2h, the furnace is cooled to below 200°C to allow air cooling.
The absolute pressure in the furnace should be no more than 0.09Pa.
3. Solution treatment
910-940℃, 0.5-2h, water quenching.
520-550°C, 2-4h, air cooling.
5. Stress relief annealing
Complete stress relief annealing: 600-650℃, 1-4h, air cooling; incomplete
stress relief annealing: 500-600℃, 0.5-3h, air cooling. Stress relief annealing
can be carried out in an air furnace or a vacuum furnace.

Europe has been facing the gas shortage problem since the second half of 2021. The worsening situation in Russia and Ukraine has reduced Russian gas shipments to Europe, leading to a doubling of European gas prices. Energy shortages have sent electricity prices soaring. For these reasons, it is predicted that the price of the Ti6Al4V Powder will continue to increase.
