Abstract

The tensile behavior of Ti-Al-Nb alloys with varying aluminium and niobium concentrations was investigated for temperature range of 25-650 °C. The effects of phase volume fraction, composition, morphology and grain size on tensile properties were also examined using single-phase microstructures. The slip and cracking observations depicted the evidence of ductile and brittle characteristics of single-phase microstructures. The analysis suggested that the room temperature (RT) tensile properties were sensitive to interstitial oxygen content and aging.
