Vacuum annealing
The hydrogen content of the titanium alloy surface layer is reduced to a safe concentration, eliminating the possibility of hydrogen embrittlement. In addition, the residual stress is reduced and the mechanical properties and performance of the alloy are ensured.
The purpose and significance of the above four heat treatments are clear, but the concepts of isothermal annealing and double annealing are often confused. Isothermal annealing and double annealing are only suitable for α+β type alloys.
