Titanium is an important structural metal developed in the 1950s, which widely used in various fields because of their high strength, good corrosion resistance, and high heat resistance. The first practical titanium alloy is Ti-6Al-4V alloy which successfully developed in 1954. Due to its heat resistance, strength, plasticity, toughness, formability, weldability, corrosion resistance and biocompatibility. It has become the flagship alloy in the titanium alloy industry, and the amount of this alloy used has accounted for 75% to 85% of all titanium alloys. Many other titanium alloys can be regarded as modifications of Ti-6Al-4V alloy.
Grade5, UNS R56400, 3.7164, Ti-6Al-4V is the most widely used α+β titanium alloy. It has excellent specific strength, excellent corrosion resistance and fracture toughness, as well as good welding processability and the ability to withstand extreme temperatures, and can be strengthened by heat treatment. The alloy was originally developed for the aerospace market and is widely used in aerospace structural components. Because of its very good biocompatibility, it has also been widely recognized in the medical industry.
