The team knew that an oxygen impurity is often used for titanium alloys to harness a potent strengthening effect. Titanium made with just a tiny increase in the amount of atomic oxygen can result in a metal with a several-fold increase in strength. Unfortunately, the oxygen can also yield an even larger decrease in the metal's ductility.Web

1. Introduction. A commercially pure (CP) titanium (Ti Grade 1–4) or a high purity (Ti 99.99%) titanium can be a good alternative to less biocompatible Ti alloys (e.g., the most commonly exploited Ti-6Al-4V) in many biomedical applications such as dental and maxillofacial implantology [1,2].However, their mechanical properties may be insufficient …Web

Iron, an inexpensive element, has a strong β-stabilizer effect and a good reinforcing effect on non-toxic and non-allergic titanium alloys . In addition, it is reported to improve the sintering reaction of titanium alloys [ 15 ] because it represents a faster diffusion rate than the atom of titanium itself in the β phase as a rapidly diffused ...Web

The separation and extraction of titanium, iron, and alumina in one spot can shorten the process and make full use of the electric energy. Under optimal conditions, the efficiencies of iron, titanium, and alumina were 97.6%, 93.1% and 88.5%, respectively.Web

Iron is usually present in commercially pure titanium as an impurity. There have been several studies of its effect on the hydrogen absorption characteristics and corrosion …Web

Uses. Titanium is as strong as steel but much less dense. It is therefore important as an alloying agent with many metals including aluminium, molybdenum and iron. These alloys are mainly used in aircraft, spacecraft and missiles because of their low density and ability to withstand extremes of temperature.Web

Microstructures and corrosion properties of pure titanium were characterized when iron was used as a grain refiner. The added Fe element acted as a strong grain refiner for pure titanium by forming β Ti phase at grain boundaries, and 0.15 wt% Fe was revealed to be a sufficient amount to make the grain size of pure titanium below 20 μm, which …Web
