Some common β titanium plate and titanium alloys

Titanium - molybdenum titanium Department
Β titanium and molybdenum having the same lattice type and molybdenum in solid solution β titanium infinite . In a solution of molybdenum titanium at 600 ℃, 0.8% , when the molybdenum content exceeds 24 ~ 28% at 650 ℃ β single phase is formed . Ti - Mo binary system in the solid state is only a ~ β polymorphic transformation. In a titanium- molybdenum solubility of increase with decreasing temperature , titanium is not a supersaturated phase decomposition problem.

2 titanium - titanium vanadium
In the solid titanium shift occurred - exactly molybdenum . Vanadium and β have the same lattice type titanium , vanadium and titanium in the β solid solution is infinite . 600 ℃, vanadium and titanium in a solid solution of 3.5%. At 650 ℃, when the vanadium content of more than 18.5 % to 20% then form a single β -phase solid solution. In the liquid - solid transition , titanium - vanadium binary liquid line appears a minimum. Solubility of vanadium in a phase of decline in tandem with temperature increase , titanium is not a relative supersaturation and its decomposition problem.

3 titanium - niobium titanium Department
Its solid-state transformation and titanium - vanadium same liquid - solid transition similar to titanium - molybdenum . Niobium and titanium infinite β solid solution .surgical implant titanium Niobium at 600 ℃ in a solution of 4% of titanium , when the Nb content exceeds about 50% of the solid solution to form a single β . Its a / a + shape titanium β phase line - molybdenum similar. Nor supersaturated solid solution decomposition problem.

4 Titanium - Tantalum Department of titanium
Tantalum is also unlimited in β titanium solid solution . 600 ℃, a degree of solid solution of tantalum and titanium is 11 % when the content of tantalum is about more than 65% to form a single β solid solution.

5 titanium - iron- titanium
Β titanium iron solubility of 25% maximum , in 1085 ℃. The maximum solid solubility of iron in a 0.5% titanium , about 590 ℃ appear , the following occurs in the eutectoid transformation temperature , the solubility of the eutectoid point of about 15% . β = a + TiFe

6 titanium - . Manganese titanium
Its titanium-rich portion of the titanium - iron binary phase diagram of the Ti-rich part similar. The maximum solid solubility of manganese in the β titanium is about 33 % in 1175 ℃. The maximum solid solubility of manganese in a titanium of about 0.5% titanium rod, in 550 ℃. Eutectoid transformation occurs at this temperature , the solubility of the eutectoid point of about 20% . β = a + TiMn
