About titanium alloys

The main constituent of titanium alloy is titanium. Titanium alloy has good heat resistance, corrosion resistance and high strength. Its specific gravity, strength and service temperature are between aluminum and steel. It has high specific strength and excellent seawater corrosion resistance and ultra-low temperature performance. It not only plays an important role in the manufacture of important structures in the aerospace industry, but also plays an important role in the manufacture of structural components of rockets, missiles and high-speed aircraft.

The heat treatment process of titanium alloy can be summarized as follows:

(1) Stress relief annealing: the purpose is to eliminate or reduce the residual stress generated during processing. Prevent chemical attack and reduce deformation in some corrosive environments.

(2) Complete annealing: the purpose is to obtain good toughness, improve processing performance, facilitate reprocessing and improve the stability of size and structure.

(3) Solution treatment and aging: the purpose is to improve its strength, α Titanium alloys and stabilized β Titanium alloy can not be strengthened and heat treated, but only annealed in production. α+β Titanium alloy and containing a small amount α Metastable phase β Titanium alloys can be further strengthened by solution treatment and aging.
