In the present study, the effect of α₂-phase (Ti₃Al) on the wear behavior of the titanium alloys is investigated by adding different amounts of (0.3-0.5%) Fe to the Ti8Al2.5Sn and Ti5Al2.5Sn alloys, which are produced by the mechanical alloying. The pre-formed green compacts were sintered at 1200°C for one hour. The sintered samples were characterized by scanning electron microscope, X-ray diffraction, and the hardness and density measurements. The wear tests were performed under 30 N load, at four different sliding distances (400-1600 m) and with a constant speed of 1 ms¯¹. As a result of the study, it was understood that the α₂-phase (Ti₃Al) in the structure occurred at the grain boundary during the sintering process. With an increase in Fe addition to the Ti8Al2.5Sn and Ti5Al2.5Sn alloys, the density and hardness of the alloy increased as well. As a result of the wear tests, it was determined that the least weight loss occurred in Ti5Al2.5Sn alloy with a 0.5% Fe addition.
