SUMMARY:

Titanium, being a biologically inert material and having low density, is the
metal most used for orthopedic implants, also being used in orthodontics and
stents, having the Ti-6Al-4V alloy as the main representative. Biomaterials need
suitable properties such as biocompatibility, corrosion resistance and
mechanics compatible with the requested efforts. However, new leagues appear as
alternatives, since the aforementioned alloy has elements that can be toxic to the
human body, and has low mechanical compatibility, mainly elastic modulus
between metal and bone, since the elastic modulus of human bone is around 30 GPa,
while that of pure titanium exceeds 100 GPa, causing a problem known as stress
shielding. Thus, new alloys such as Ti-16Nb-10Hf, containing non-toxic elements, are
have the potential to overcome the limitations of the currently used alloys. In this
phase transformation temperatures and properties will be characterized
mechanical properties of the Ti-16Nb-10Hf alloy. These characterizations will serve as a reference for the
development of thermomechanical treatments that control the microstructure of this alloy
aiming to achieve optimized properties for biomedical applications.
