Heat treatment of GR23 titanium tubing

The commonly used heat treatment methods for GR23 titanium pipe are annealing, solid solution and aging treatment. Annealing is to eliminate internal stresses, improve plasticity and organizational stability, in order to obtain a better overall performance. Usually α alloy and (α + β) alloy annealing temperature is selected in (α + β) - → β phase transition point below 120 ~ 200 ℃; solution and aging treatment is from the high temperature zone fast cooling, in order to get the martensite α ′ phase and the sub-stable β phase, and then in the medium temperature zone heat preservation so that the sub-stable phase decomposition, get the α phase or compounds and other small diffuse second phase of the point, so as to make the alloy to strengthen the purpose.
