    Full Text Available Systematic investigations of tensile properties of alpha + beeta type high temperature Ti alloy VT9 (Ti-6 Al-3.3 Mo-1.65 Zr-0.3 Si wt. per cent developed on ageing at 803, 823 and 853 K for 2, 6 and 121 hr, respectively following the solution treatment in alpha + beeta phase field at 1233 K for 1 hr and air cooling, show that the highest tensile strength values are obtained on ageing at 823 K for 6 or 12 hr. In view of the shorter duration of ageing, the ageing treatment at 823 K for 6 hr is considered appropriate stabilisation treatment for this alloy. The tensile strength values of the alloy VT9 from the newly-established stabilisation treatment are considerably higher than those resulting from the earlier reported stabilisation treatment (at 803 K for 6 hr, in particular at room temperature.

    The present paper presents a method of analysis of titanium alloys plastic properties under severe deformation conditions during milling with registration of the cutting force components Fx, Fy, Fz in real time using a special stand. The obtained constitutive relations in the form the Johnson-Cook law for stresses and dependence for a friction coefficient describing the titanium alloy VT9 plastic properties under simulate operating conditions.
