Grain-Structure Refinement in Titanium-Alloy Under Different Loading Schedules
The dependence of the kinetics of globularization of the lamellar structure in titanium alloy VT9 (Ti-6.6% Al-3.5% Mo-1.7% Zr-0.27% Si) on the character of high-temperature loading was investigated. It was found that monotonic methods of loading (tension, torsion, tension with simultaneous torsion) were more effective means of refining the structure than non-monotonic ones (reverse torsion, torsion alternate with tension, multiaxial forging).
