Titanium is well known for its extremely tough characteristics in severe environments with specific applications in the chemical process industry, energy, desalination, military and many more.
The most important properties of titanium in relation to corrosion resistance are its immunity to both pitting and stress corrosion.
Titanium powder metallurgy can produce high performance and low cost titanium parts. Compared with those by conventional processes, high performance P/M titanium parts have many advantages: excellent mechanical properties, near-net-shape and low cost, being easy to fabricate complex shape parts, full dense material, no inner defect, fine and uniform microstructure, no texture, no segregation, low internal stress, excellent stability of dimension and being easy to fabricate titanium based composite parts.
The commercial production of titanium plate, sheet, strips, and bars is carried out using hot and cold rolling mills to achieve the necessary reductions and desired shapes. Rolling may be defined as the reduction of the cross-sectional area of a piece by compressive forces applied through rolls.
Cold rolling is carried out at temperatures below which the rate of strain hardening is greater than the rate of recrystallization. When reduction is carried out above such a temperature, the process is termed hot rolling. The major quantity of titanium plate, sheet, strips and bars is processed using hot rolling techniques.
Hot and cold working or shaping of the titanium alloys involves forging, rolling, extrusion, drawing, spinning, and other such operations.
Operations such as forging and rolling, in which the basic ingot is processed into standard forms of billets, sheet, plate, rod, and wire, will be referred to as primary forming operations. Bending, extrusion, drawing, spinning, in which these standard forms are further fabricated, will be referred to as secondary operations.
