In this study, the in vitro degradation behaviour of titanium–tantalum (Ti–Ta) alloys (10–30wt.% Ta) was investigated and compared with conventional implant materials, i.e., commercially pure titanium (Cp-Ti) and titanium–aluminium–vanadium (Ti6Al4V) alloy. Among the three Ti–Ta alloys studied, the...
