What is titanium alloy GR17 (TA8-1)
Titanium alloy GR17 (TA8-1) (Ti-0.05Pd) is an α-β titanium alloy containing approximately 90% titanium, 8% aluminum and 1% iron with good physical/mechanical properties and corrosion resistance. alloy. The addition of palladium not only significantly improves the corrosion resistance of the alloy in reducing media, but also improves its corrosion resistance in oxidizing media.
GR17 titanium alloy has comprehensive mechanical properties such as high melting point, non-magnetic, low thermal expansion coefficient, high specific strength (the ratio of the material's strength to its density) and high specific stiffness (the ratio of the material's elastic modulus to its density), and GR17 titanium alloy also has It has many excellent properties such as good corrosion resistance and resistance to biological erosion.
It is similar in performance to TA9-1, with the main difference being the palladium content. The presence of palladium helps improve the corrosion resistance of the alloy. TA8-1 has good formability and is easy to weld. It exhibits very good corrosion resistance in highly oxidizing and mildly reducing environments. This material is suitable for castable applications such as valves and fittings.
Welding of titanium alloy GR17
For the welding of titanium alloy GR17 , it has good weldability. Because it is a single-phase material, its microstructure is not affected by heat treatment or welding temperatures. The welding process is therefore relatively simple and does not adversely affect the properties of the material. So you can weld with confidence .
Annealing of Titanium Alloy GR17
titanium alloy GR17 can be carried out through the following steps:
Heat to 650-760°C (1202-1400°F) and hold for 6 minutes to 2 hours.
Then air cooling is carried out, that is, the material is exposed to the natural environment and allowed to gradually cool down.
If you need to relieve stress, you can do the following:
Heat to 480-595°C (896-1103°F) and hold for 15 minutes to 4 hours.
Then carry out air cooling.
The annealing process can help restore the material's grain structure and reduce stress. Remember to strictly control the heating and cooling speeds according to specific conditions and requirements.
