Zusammenfassung: | Recent studies have been done to achieve biomedical alloys containing non-toxic elements
and presenting low elastic moduli. It has been reported that Ti-Nb-Zr alloys rich in beta phase,
especially Ti-13Nb-13Zr, have potential characteristics for substituting conventional materials such
as Ti-6Al-4V, stainless steel and Co alloys. The aim of this work is to study the internal friction (IF) of
Ti-13Nb-13Zr (TNZ) alloy due to the importance of the absorption impacts in orthopedic
applications. The internal friction of this alloy produced by arc melting was measured using an
inverted torsion pendulum with the free decay method. The measurements were performed from 77 to
700 K with heating rate of 1 K/min, in a vacuum better than 10-5 mBar. The results show a relaxation
structure at high temperature strongly dependent on microstructure of the material. Qualitative
discussions are presented for the experimental results, and the possibility of using the TNZ as a high
damping material is briefly mentioned. |
