TC10 Alpha-Beta Titanium Alloy

TC10 is a Chinese α+β titanium alloy. (Note: the source page lists a Ti-6Al-4V-type composition identical to TC4, which appears to be a copy-paste error — the actual TC10 grade is a higher-alloyed near-β titanium. Verify composition against the mill certificate before publication.)

Overview

• Material: TC10 — α+β / near-β titanium alloy
• Available forms: Bar, plate, sheet, tube, wire and forgings

Chemical Composition (wt%) — PER SOURCE, PLEASE VERIFY

Other elements: each ≤ 0.10 %, total ≤ 0.40 %. This matches TC4 / Ti-6Al-4V and is likely incorrect for TC10 — replace with actual TC10 (Ti-5Al-4Mo-2Cr-2.5Fe-type) composition.

Physical Properties

Mechanical Properties (annealed)

Key Features

• High strength with good ductility and high specific strength;
• Strong corrosion resistance against many media;
• Good hot strength for long-term service at 400 °C;
• Good cryogenic toughness;
• Good weldability.

Fabrication & Heat Treatment

• Melting: vacuum arc remelting (VAR) for uniform composition and low impurities.
• Hot working: forged, rolled or extruded at 850–1000 °C with controlled heating.
• Cold working: cold rolled and cold drawn; intermediate annealing at approx. 650–700 °C.
• Welding: TIG welding after thorough cleaning and with suitable shielding.
• Annealing: 700–800 °C for 1–2 h, air cool.
• Solution treatment & ageing: solution treat at 900–950 °C then rapid cool; age at 500–550 °C to raise strength.

Typical Applications

• Aerospace: spars, frames, wing panels, engine fan discs and blades, landing gear; spacecraft structures and engine parts;
• Petrochemical: reaction towers, heat exchangers, piping and valves;
• Shipbuilding: propellers, shafting and seawater piping;
• Medical: artificial joints and bone-fixation devices.
