Abstract: In this study, Ti6Al4V (Grade 5) alloys were first dissoluted at 850 degrees C for 120 min and then were aged at 250, 350, 450, 550, 650, and 750 degrees C, respectively. After each aging duration (by looking at hardness ratios aged between 9 to 54 hours), the hardness of the samples was measured. Depending on the aging temperature and time increase, hardness increased upon the formation of 0' phases. After the formation of 0' phases, the hardness started to decrease. The highest hardness value was measured in the sample aged at 450 degrees C for 24 hours. The wear behavior of the untreated and the aged samples was investigated through a detailed pin- on-disc test. The effect of the aging temperature on the volume loss, the specific wear rate, and the coefficient of friction were examined. Metallographic analyses were performed before and after the wear tests. Both abrasive and adhesive wear formations were observed on the FESEM-EDS images of the worn surfaces. When the results were evaluated, it was observed that the highest hardness and good wear behavior were obtained for the samples aged at 450 degrees C for 24 hours.
