Anisotropy of <a> slip behaviour in single-colony lamellar structures of Ti-6Al-4V

Micro-tensile tests on single-colony specimens of Ti-6Al-4V alloy with a fine lamellar microstructure revealed that the critical resolved shear stress of the basal slip was lower than that of the prismatic slip. This has been attributed to easier slip transmission within the habit plane at the α/β boundaries.
