N2 - Linear friction welding is employed to weld a Ti2AlNb-based alloy. The oxidation behavior of three different zones, i.e., base metal, weld zone, and thermo-mechanically affected zone is studied at 800 °C exposed to air. The oxidation kinetics of the specimens consist of an initial parabolic kinetic and followed by a linear kinetic. For the base metal, absorption of more oxygen due to higher amount of α2 phase leads to the thickest oxidation scale, while the preferential formation of Al2O3 for the joint contributes to better oxidation resistance. The presence of AlNbO4 for all the three zones can be observed after a prolong exposure in air, leading to a drastic acceleration of oxidation rate.
