Abstract

The tensile properties of extruded Ti-6Al-4V-xB alloys (wt.%) were evaluated in an orientation perpendicular to the extrusion direction at room-temperature and 455 °C. The extrusion process preferentially oriented the basal plane of α-Ti perpendicular to the extrusion axis. This strong α-phase texture resulted in tensile anisotropy. The tensile strength in the transverse orientation was lower than that in the longitudinal orientation, but it remained greater than that for the as-cast Ti-6Al-4V. The TiB phase was aligned in the extrusion direction and increased B content was found to weaken the α-phase texture, causing a weakening of tensile anisotropy. Debonding was not observed during the tensile tests in the transverse orientation, indicating a strong interface bond exists between the TiB phase and the two-phase (α + β) Ti-6Al-4V matrix.
