We have studied the compressibility and stability of different β-titanium alloys at high pressure, including binary Ti–Mo, Ti–24Nb–4Zr–8Sn (Ti2448) and Ti–36Nb–2Ta–0.3O (gum metal). We observed stability of the β phase in these alloys to 40GPa, well into the ω phase region in the P–T diagram of pure titanium. Gum metal was pressurised above 70GPa and forms a phase with a crystal structure similar to the η phase of pure Ti. The bulk moduli determined for the different alloys range from 97 ± 3GPa (Ti2448) to 124 ± 6GPa (Ti–16.8Mo–0.13O).
