Other β titanium and titanium plate series of

1 titanium - titanium chromium
And titanium - iron, titanium - different manganese , chromium solid solution in β titanium unlimited . There is a minimum point of chromium liquid line - in titanium. Chromium and titanium in a maximum solubility of about 0.5% , in 670 ℃. Here the presence of the following eutectoid transformation temperature , the solubility of the eutectic point of 15 %. β = a + TiCr2
TiCr2 is an intermetallic compound having a face centered cubic lattice in a low temperature , a = 6.940 Å ; having a hexagonal lattice at a high temperature , a = 4.900 Å , c = 7.927 Å , c / a = 1.6178, a melting point of 1350 ℃.

2 titanium - titanium copper lines
Copper maximum solid solubility of β titanium is 17 % in 990 ℃. And the maximum solid solubility of titanium in a 2.1% in 798 ℃. This occurs in the following eutectoid transformation temperature , the solubility of its eutectic point was 7.1 %. β = a + Ti2Cu
Titanium - titanium-rich portion of the copper-based compounds are the most important Ti2Cu, may occur only when the copper content of more than 40% TiCu phase .

3 titanium - tungsten titanium Department

Titanium - tungsten and titanium - chromium similar in β titanium tungsten is infinite solid solution . In the solid state , it is only one eutectoid transformation : β = a + β2
Its solubility eutectoid point about 28 % eutectoid temperature of 715 ℃. β2 -phase solid solution of tungsten is based. In the eutectoid temperature , solubility in tungsten titanium reaches a maximum of 0.8 %. Clearly, in titanium - tungsten no intermetallic compounds appear.

4 titanium - . Cobalt titanium

Cobalt β titanium maximum solubility of 17% in 1020 ℃. The maximum solid solubility of cobalt and titanium in a range of 1.0 % in 685 ℃. This occurs in the following eutectoid transformation temperature , the solubility of the eutectoid point was 9.5 %. β = a + Ti2Co
Titanium - cobalt titanium-rich part of the binary phase diagram has between two metal compounds : Ti2Co and TiCo. The former is the analysis of the product of the latter only in 38% or more of cobalt .

5 titanium - nickel titanium alloy

Nickel solid solution of β titanium maximum of 13 % in 955 ℃. Nickel- titanium in a solution of 0.2% maximum , in 770 ℃. This occurs in the following eutectoid transformation temperature medical titanium plates, its solubility eutectoid point to 5.0 %. β = a + Ti2Ni
Titanium - nickel titanium-rich part of the binary phase diagram between the two main metal compounds : Ti2Ni and TiNi. The former is eutectoid product , which exists only when more than 38% of nickel .

6 titanium - . Palladium titanium

Palladium maximum solid titanium β of about 49.94% , in 1140 ℃. Palladium and titanium in a solution of about 2.41% maximum , in 578 ℃. In the presence of the following eutectoid transformation temperature , the solubility of the eutectoid point to 24.92% . β = a + Ti4Pd
Obviously , titanium - titanium-rich part of the binary phase diagram of palladium only one intermetallic compound.

7 titanium - titanium silicon

Si in solid solution of β titanium maximum of about 3.0 % in 1340 ℃. A maximum solid solubility in silicon in an amount of 0.45% titanium , in 860 ℃. This occurs in the following eutectoid transformation temperature , its solubility eutectoid point to 0.65 percent . β = a + Ti3Si
Clearly, in titanium - the presence of silicon binary phase diagram of titanium-rich part of the two compounds : Ti3Si and Ti5Si3. The former is a low-temperature phase .titanium wire The latter is the high temperature phase , or a silicon content of more than 16.8% at room temperature exists.
