Beta-Ti alloys based on the Ti-Nb system are promising candidates to replace alpha and alpha+beta alloys in the field of load-bearing bone implants, because of their superior properties, such as a low Young’s modulus and good biocompatibility. One goal is to further improve their mechanical properties towards higher static and dynamic strength.
The focus of this work is to investigate the influence of different thermomechanical processing routes on the microstructure and mechanical properties for the beta Ti-40Nb alloy. SEM, EBSD and XRD are used to analyze the effect of different cold-rolling and annealing steps on the evolution of phase composition, texture and grain structure. The mechanical properties are characterized using microhardness, tensile and fatigue tests. Grain refinement, e.g., leads to an increase of the yield strength of 35 %, compared to the solution treated state.
This work is funded by the DFG as part of SFB/Transregio 79.
