Heat Treatment

Titanium alloys are subjected to enhanced heat treatment, that is, solid solution and aging treatment. This process can significantly improve the strength of the alloy, and the purpose is to obtain comprehensive properties of high strength and good plasticity. Titanium alloy strengthening heat treatment consists of two steps of solution treatment and aging. This is a rather complicated process. The residual α phase remains unchanged when quenched and heated at high temperature, and the β phase can be transformed into α, α” and ω according to the alloy composition. , β and other metastable phases, these metastable phases transform into dispersed (α+β) phases during the aging process, which makes the alloy significantly strengthened.

Strengthening heat treatment of titanium alloy is limited by alloy phase composition

Most near-α-type and stable β-type titanium alloys (except for a few such as Ti-2Cu) cannot be strengthened by heat treatment, and only α+β-type titanium alloys can be strengthened by heat treatment.

Strictly control the heating temperature and time

When the titanium alloy is heated above the β transformation temperature, the grain [iii] grows rapidly; in the subsequent cooling, the α phase first nucleates [iv] and grows on the grain boundary, and grows to the inside of the grain. The β grain size obtained after heat treatment in the β zone is relatively large, generally reaching the level visible to the naked eye. Moreover, the coarse-grain [v] structure of titanium alloy cannot be eliminated by heat treatment, and the structure must be changed by forging deformation. Therefore, when heating before forging or heat treatment in the β zone, the heating temperature and time should be strictly controlled to prevent excessive grain growth.
