[2025-10-02T06:43:47.660494] [PI reasoning] **Determining alpha phase stabilizer**

I’m looking at a multiple-choice question about the titanium alloy Ti-6Al-4V. In this alloy, aluminum acts as the alpha phase stabilizer, while vanadium serves as the beta stabilizer. Since the question asks for the stable element in the alpha phase, that would be aluminum. So, I’ll select option B for my answer. To support this, I might cite a source discussing titanium stabilizers, possibly looking into a relevant text or paper.
