Abstract Scope A reliable database regarding the fatigue properties of an implant alloy is one key factor for a successful application in the human body. Identification of potential failure causes is consequently very important for a more reliable fatigue life prediction of already existing and new metallic implant materials. Thus, this work focuses on fatigue testing of new metastable binary Ti-Nb-alloys including detailed analysis of the fracture surfaces with SEM, EDX and FIB. Furthermore, broad numbers of in-vivo tested CP-Titanium (ASTM Grade 4) osteosynthesis plates (rat model) were subject to in-depth failure analysis after explantation. Results revealed a complex damage condition where the high notch sensitivity of Ti-based alloys is the major reason for early failure or severe damage in most of the cases. Fatigue data for the new alloy generation is promising provided that the notch influence can be controlled. Funded by the German Research Foundation (DFG) under SFB/Transregio 79.
