What are the heat treatment processes of analytical titanium coils?
Commonly used heat treatment methods for titanium coils include annealing, solid solution and aging treatment. Annealing is to eliminate internal stress, increase plasticity and structural stability to obtain better overall performance. Usually a close
The annealing temperature for gold and (a+β) alloys is selected to be 120 ~ 200 °C below the (a+β)-→β phase transformation point; the solution and aging treatment are rapid cooling from the high temperature zone to obtain martensite a'phase And the metastable β phase, and then heat preservation in the middle temperature zone to decompose these metastable phases to obtain a phase or compound and other finely dispersed two-phase particles, which is in line with the purpose of strengthening the alloy.
The heat treatment process of the product can be summarized as:.
1. Solution treatment and aging: The purpose is to increase its strength. Titanium coils and stable titanium coils cannot be strengthened heat treatment, and only annealing is carried out in production. A+ products and metastable B products containing a small amount of phase a can further strengthen the alloy through solution treatment and aging.
2. Complete annealing: The purpose is to obtain good toughness, improve processing performance, and facilitate reprocessing and increase the stability of the size and structure.
3. Stress elimination annealing: the purpose is to eliminate or reduce the residual stress generated during processing. In order to avoid chemical corrosion and reduce deformation in some corrosive environments.
In addition, in order to meet the specific requirements of the workpiece, industrial titanium coils also use metal heat treatment processes such as double annealing, isothermal annealing, β heat treatment, and deformation heat treatment.
