Due to reduced stiffness, research on second
generation titanium alloys for implant applications, like the
metastable βtitanium alloy Ti15Mo, become more and more
important in the recent years. The machinability of these alloys is
generally poor leading to problems during implant production and
comparably large production costs. Therefore, in the present study,
Ti15Mo was alloyed with 0.8 wt. of the rare earth metals
lanthanum (Ti15Mo0.8La) and neodymium (Ti15Mo0.8Nd) to
improve its machinability. Their microstructure consisted of a
titanium matrix and micrometersize particles of the rare earth metals
and two of their oxides. The particles stabilized the microstructure as
grain growth was minimized. As especially the ductility might be
affected by the precipitates, the behavior of Ti15Mo0.8La and Ti
15Mo0.8Nd was investigated during static and dynamic
deformation at elevated temperature to develop a processing route.
The resulting mechanical properties (static strength and ductility)
were similar in all investigated alloys.
