Metastable β titanium alloys have drawn considerable attention due to their outstanding strength-to-weight ratio. In particular, the Ti-10V-2Fe-3Al alloy is extensively employed in the aircraft industry. Tensile tests at room temperature with different sampling directions highlighted a marked anisotropy which is still poorly understood. The present study focused on the role of the high fraction of β retained at room temperature. In particular, features including the β grain morphology and the crystallographic texture of the β phase were considered using scanning electron microscopy, electron back-scattered diffraction and in situ optical microscopy tensile tests combined with digital image correlation. Significant deformation and damage heterogeneities have been observed in relation to the crystallographic orientation of the β phase and the slip length within β grains. The outcomes of this study demonstrate that the millimeter-sized β grains primarily govern the mechanical anisotropy in Ti-10V-2Fe-3Al.
