A new material for mechanical transmission shaft modified with graphene was prepared by ultrasonic wave vibration assisting. The new material was analyzed by OM, SEM and XRD, and the mechanical properties andwear resistance were tested. The results show the new material is composed of α-Fe matrix, TiC phase and grapheme, which has excellent mechanical properties and wear resistance. Compared with the commercial steel of 40Cr, the yield strength, tensile strength, elongation and impact energy of the new material can increase by 47.1%, 41.9%, 46.2%, and 46.9%, respectively. The wear volume of the new material at -40~C, 20℃ and 80℃ can decrease by 49.0%, 45.9%, and 55.8%, respectively.
