I have a question regarding Titanium alloys. We have a tube component made of Ti 6Al-4V, and we nitride the tube at 1450F. After nitriding we are seeing a 0.003”-0.004” expansion in the diameter of the tube, which is not suitable for our application. Can anyone please suggest another Titanium alloy which would not produce such growth? We were thinking of pure alpha Titanium, and see if it grows the same. Please advise. Any suggestion is greatly appreciated.
