By utilizing the different characteristics of the two aforementioned titanium structures, appropriate alloying elements are added to gradually alter the phase transformation temperature and phase content, thereby obtaining titanium alloys with different microstructures.
Titanium alloys are alloys based on titanium with other elements added. According to the phase composition in the room temperature microstructure, titanium alloys are mainly divided into the following three categories:
1. α-type titanium alloys (TA series): Mainly composed of α-phase solid solution, containing α-phase stabilizing elements (such as aluminum, oxygen, nitrogen, etc.). This type of titanium alloy has a stable structure, higher wear resistance than pure titanium, strong oxidation resistance, and can maintain strength and creep resistance at temperatures of 500℃~600℃. However, its room temperature strength is relatively low, and it cannot be strengthened by heat treatment.
2. β-type titanium alloys (TB series): Mainly composed of β-phase solid solution, with added β-phase stabilizing elements (such as molybdenum, vanadium, chromium, iron, etc.). This type of titanium alloy has high strength without heat treatment, and the strength is further improved after quenching and aging, but the thermal stability is poor, and it is not suitable for use at high temperatures.
3. α+β-type titanium alloys (TC series): Containing both α and β stabilizing elements (such as aluminum, molybdenum, vanadium, etc.), it is a duplex alloy. It has excellent comprehensive properties, good toughness, plasticity and high-temperature deformation performance, and can be quenched and aged to strengthen the alloy, with a wide range of applications. Among them, TC4 (Ti-6Al-4V) titanium alloy is more commonly used, accounting for more than 50% of the titanium alloy usage.
The classification system of titanium alloys is established by the national standard GB/T 3620.1 of China and has been widely recognized internationally.
