Metastable beta-type Ti-Nb alloys are multi-purpose candidate materials for biomedical applications. They exhibit a number of beneficial features that partially stem from their relatively low Young’s modulus and the high ductility effecting easy adaption of various geometrical shapes by metal forming processes.
In this work we used a combination of X-ray diffraction, differential scanning calorimetry, dilatometry and transmission electron microscopy to establish phase transformation sequences and thermal stability of a series of binary Ti-Nb alloys with nominal Nb contents ranging from 14 to 45 wt. %. The influence of Nb addition on the structural characteristics of martensitic phases in the Ti-Nb system was studied in detail. We used X-ray diffraction combined with Rietveld-based analyses to investigate the gradual structural changes of α' and α’’ martensites effected by addition of Nb and determined their compositional boundaries.
