Niobium is also a fairly dense element and it is this density that might account for its apparent rarity. Occurring at only twenty parts per million, it is 33 rd in the hall of fame of most common elements in the Earth's crust. This surprisingly low value might arise from the 'missing' niobium sinking to the Earth's core during the planet's ...

One of the most promising materials for future orthopedic implants is Titanium-Niobium-Zirconium-Tantalum alloy (TNZT) [17,20,21,22,23,24]. This high entropy titanium alloy has a lower elastic modulus than Ti-6Al-4V, and is even less likely to corrode in the body than Ti-6Al-4V. It is still strong enough to withstand typical loading seen by …
