The deformation and aging characteristics of Ti-V alloys and Ti-12 12 wo Mo alloy were investigated. Single crystals of Ti-30V, Ti-40V and Ti-12 12 Mo were used to study deformation behavior for the solid solution condition and after an aging treatment. The critical resolved shear stress for slip or twinning was determined as a function of temperature for these crystals. Optical trace analysis was used to identify the active slip or twinning plane and thin foil electron microscopy was used to identify aging products. X-ray precession camera techniques were occasionally used to corroborate results. Tests were also conducted to determine the effect of grain size on yield stress and work hardening behavior in Ti-20V, Ti-30V, and Ti-40V alloys.
