Titanium alloys were widely used in the aerospace field in the early days, mainly in the production of aircraft engines or pneumatic components. Later, with the continuous and in-depth development of technology, titanium alloys have entered the lives of ordinary people, and titanium alloys are also used in factories or household devices. Now countries and institutions are scrambling to develop new titanium alloys, which have the characteristics of low cost and high performance. In recent years, the new development of titanium alloys is mainly concentrated in the following aspects.
(1) Medical titanium alloy.
Titanium alloys have low density and good biocompatibility. They are ideal medical materials and can even be implanted into the human body. Titanium alloys previously used in the medical field contain vanadium and aluminum, which can cause harm to the human body. However, recently, Japanese scholars have developed a new type of titanium alloy with good biocompatibility, but this alloy has not yet been mass-produced. It is believed that such high-quality alloys can be widely used in daily life in the near future.
(2) Flame retardant titanium alloy.
Titanium-based alloys that can resist combustion under certain pressure, temperature and air flow rate are resistive titanium alloys. The United States, Russia and China have successively developed new resistance titanium alloys. The United States applies these resistance titanium alloys to engines. Because these titanium alloys are not sensitive to combustion, the stability of the engine can be greatly improved.
(3) High temperature titanium alloy.
Combining the rapid solidification method and the powder metallurgy method, the titanium alloy prepared by the fiber or particle reinforced composite material has excellent high temperature mechanical characteristics. The service temperature limit of high temperature titanium alloy is much higher than that of ordinary titanium alloy. At present, a new type of high-temperature Grade 3 Pure Titanium Sheet has been prepared in the United States.
