From the solid state, the titanium alloys might be arranged in either hexagonal close-packed (alpha) or body-centered cubic (beta) structure. Pure titanium undergoes an allotropic transformation from hexagonal close-packed (HCP) alpha titanium to body-centered cubic (BCC) beta titanium as its heat is raised by means of 882 C (1620 F). The melting stage of pure titanium is 1668 C (3034 F) and titanium products. Aluminum may be the most broadly utilised alloying component in titanium-based alloys. It’s the only real typical metal that raises the beta transus temperature and have huge solubilities in both the alpha and beta stages.

Aspects such as aluminum, oxygen, nitrogen, carbon, gallium, germanium, lanthanum, and cerium stabilize the alpha stage to increased temperature and therefore are therefore called alpha stabilizers.

In common, transition metals and noble metals (i.e., metals which, like titanium, have unfilled or just-filled d-electron bands) might be stabilizers of the beta stage to decrease temp and so are therefore often called beta stabilizers.

Beta stabilizers really are subdivided into two groups: beta-isomorphous (e.g. vanadium, niobium, tantalum, molybdenum, and rhenium) and beta-eutectoid (e.g., copper, silver, gold, palladium, indium, lead, bismuth, chromium, tungsten, manganese, iron, cobalt, nickel, uranium, hydrogen, and silicon).

Vanadium, molybdenum, and niobium will be the most often utilised beta-isomorphous developing aspects in titanium-based alloys. These elements, when added in enough concentrations, can stabilize the beta phase to room temperature. Tantalum and rhenium, which are also beta-isomorphous forming elements, can be rarely utilized, mainly due to their higher densities.

Chromium, iron, and silicon really are the only beta-eutectoid forming things which are normally used in quite a few titanium-based alloys and titanium sources.

Zirconium, hafnium, and tin form a team of alloying aspects recognized as neutral additions. These three components are at times classified as beta stabilizers, while they depress the beta transus heat (albeit only somewhat) within their respective binary phase diagrams with titanium. Zirconium and hafnium will most certainly be isomorphous with titanium and exhibit a similar beta to alpha allotropic phase transformations. Those two components have full solubilities inside alpha and beta stages of titanium. Tin is really a beta-eutectoid developing aspect and its impact around the beta transus temperatures is negligible for all sensible applications.
