Titanium alloy rod is a kind of slender part made of titanium alloy, which can be used for construction engineering, interior decoration and so on by secondary processing. It has the advantages of light weight, high strength and beautiful appearance, and is widely used in modern construction.

Titanium alloy rod technical requirements

1: The chemical composition of titanium and titanium alloy bars shall comply with the provisions of GB/T 3620.1. When the buyer re-inspects, the allowable deviation of the chemical composition shall comply with the provisions of GB/T 3620.2.

2: The diameter or side length of the hot-worked bar and its allowable deviation shall meet the requirements of Table 1.

3: After hot processing, the bar is turned (ground) and cold-rolled, and the allowable deviation of the diameter of the cold-drawn bar should meet the requirements of Table 2.

4: The out-of-roundness of the bar that has been turned (ground) after hot processing should not be greater than half of its dimensional tolerance.

5: The indefinite length of the processed bar is 300-6000mm, the indefinite length of the annealed bar is 300-2000mm, and the fixed or double length should be within the range of the indefinite length. The allowable deviation of the fixed length is +20mm ; The length of the double ruler should also be included in the incision amount of the bar, and the amount of each incision is 5mm. The length of the fixed length or the double ruler should be indicated in the contract.

alloying

Titanium alloys are alloys based on titanium with other elements added. Titanium has two kinds of isomorphous crystals: α titanium with close-packed hexagonal structure below 882 °C, and β titanium with body-centered cubic structure above 882 °C.

Alloying elements can be divided into three categories according to their effect on the transformation temperature:

① The elements that stabilize the α phase and increase the phase transition temperature are α stable elements, such as aluminum, carbon, oxygen and nitrogen. Among them, aluminum is the main alloying element of titanium alloy, which has obvious effects on improving the normal and high temperature strength of the alloy, reducing the specific gravity and increasing the elastic modulus.

② The elements that stabilize the β phase and reduce the phase transition temperature are β-stabilizing elements, which can be divided into two types: isomorphic and eutectoid. Products using titanium alloys

The former has molybdenum, niobium, vanadium, etc.; the latter has chromium, manganese, copper, iron, silicon and so on.

③ The elements that have little effect on the phase transition temperature are neutral elements, such as zirconium and tin.

Oxygen, nitrogen, carbon and hydrogen are the main impurities in titanium alloys. Oxygen and nitrogen have greater solubility in α phase, which has a significant strengthening effect on titanium alloys, but reduces the plasticity. Usually, the content of oxygen and nitrogen in titanium is 0.15-0.2% and 0.04-0.05% or less, respectively. The solubility of hydrogen in the α phase is very small, and too much hydrogen dissolved in the titanium alloy will produce hydride, which will make the alloy brittle. Usually, the hydrogen content in titanium alloys is controlled below 0.015%. The dissolution of hydrogen in titanium is reversible and can be removed by vacuum annealing.
