Detailed Analysis Of TC19 Titanium Alloy Processing Technology

I. Forging technology
Forging process selection:
The forging of TC19 titanium alloy usually adopts two main processes: conventional β forging + (α + β) forging and high - low - high forging (i.e. β forging + (α + β) forging + β forging). Both processes can prepare TC19 titanium alloy rods with fine and uniform microstructure, in which the mechanical properties of the rods obtained by the high-low-high forging process are superior.
During the forging process, TC19 titanium alloy will form uniformly distributed equiaxial primary α organization on the β-transformation matrix, and this microstructure helps to improve the mechanical properties of the material.

Forging material preparation:
For the preparation of TC19 titanium alloy, first-grade titanium sponge is selected as the raw material, and the alloying elements Al, Sn and Mo are added in the form of Ti-Al-Sn-Mo intermediate alloy, and Zr is added in the form of zirconium chips with 99.7% purity.
After mixing motor pressing and other processes, three times VAR melting was carried out, and Φ360mm TC19 alloy ingots were trial produced using 1-ton vacuum self-consumption electric arc furnace.
Second, heat treatment technology
Double annealing (DA) treatment:
Double annealing treatment is carried out on forged bars to optimize their microstructure and mechanical properties. The quality of double annealed products can meet the technical requirements of MIL-T-9047.
Solid solution aging (STA) treatment:
Solid solution aging treatment is another commonly used heat treatment, through the combination of solid solution treatment and aging treatment, can further improve the mechanical properties of TC19 titanium alloy. The quality of TC19 titanium alloy bar products treated by solid solution aging treatment all meet the requirements of AMS4981 and MIL-T-9047 standards.
Other processing technologies
Mechanical processing:
TC19 titanium alloy in the machining process, need to take into account its high strength and high hardness characteristics, select the appropriate cutting tools and cutting parameters to ensure the machining accuracy and surface quality.
Surface treatment:
According to the specific application requirements, TC19 titanium alloy may also require surface treatment, such as anodizing, spraying, etc., to improve its corrosion resistance and aesthetics.
IV. Processing technology characteristics
High strength and high toughness:
TC19 titanium alloy achieves a good combination of high strength and high toughness by optimizing the alloy composition and heat treatment process, and is suitable for occasions with high requirements for mechanical properties.
Good processing performance:
Although TC19 titanium alloy has high strength and hardness, it can obtain good machining performance through reasonable forging and heat treatment process to meet the machining needs of various complex shape parts.
Wide range of applications:
TC19 titanium alloy is widely used in the manufacture of key components in aerospace, marine engineering, chemical industry and other fields due to its excellent performance.
In summary, the processing technology of TC19 titanium alloy covers many aspects such as forging, heat treatment and possible machining and surface treatment. Through reasonable process selection and parameter control, TC19 titanium alloy products with excellent mechanical properties and processing performance can be obtained.
