1. What is Titanium alloy GR9?

Titanium alloy GR9 is Ti-3Al-2.5V, and its composition contains 3% Al and 2.5% vanadium. At room temperature, the strength of titanium alloy GR9 is higher than that of pure titanium, and its corrosion resistance is strong, its strength is high, and its heat resistance is good.

2. Titanium GR9 forging process.

Forging is the use of titanium alloy molding, under pressure and impact, change the internal structure of the material to improve the mechanical properties of titanium alloy.

3. Titanium GR9 heat treatment

Titanium alloy forgings are usually air-cooled after forging. However, depending on the type of titanium alloy and the strength and plasticity required for the part, heat treatment is sometimes performed after forging. There are mainly the following kinds of post-forging heat treatment of titanium alloy:

• Incomplete annealing This annealing is mainly used to eliminate the residual stress after forging, and air cooling after annealing.
• Complete annealing This annealing can effectively eliminate the residual stress after forging.
• isothermal annealing This annealing is suitable for two-phase titanium alloys with a high content of β-stable elements. This annealing can not only eliminate the stress generated in forging, but also change the phase composition of titanium alloy, and its effect is to stabilize the microstructure properties of titanium alloy.
