TC6 is a kind of two-phase titanium alloys with complex microstructure , with the advantages of low density, high strength, corrosion resistance, but the material cost is expensive, difficult forging processing forming.

Ordinary annealed state TC6 titanium alloy under 300 °C / 5000 h has a good organization and performance stability, different temperature transient high temperature properties such as tensile, creep and lasting and double annealing and isothermal annealing state. By the normal annealing treatment of TC6 titanium alloy semi-finished products can satisfy the use of aircraft structure temperature (below 300 °C).
