TC4, TC6, TC11, TC18 titanium alloy rod and heat treatment process

There are three types of heat treatment processes for titanium rods and titanium alloy rods:

1) Solution treatment and aging: The purpose is to increase the strength. The α-titanium alloy and the stabilized β-titanium alloy cannot be subjected to tempering heat treatment, and only annealing is performed in production. The α+β titanium alloy and the metastable β titanium alloy containing a small amount of α phase can further strengthen the alloy by solution treatment and aging.

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

3) Complete annealing: The purpose is to obtain good toughness, improve processing properties, facilitate reprocessing and improve dimensional and tissue stability.
