The production process of various titanium alloy grades generally includes the following key steps:
Raw Material Preparation: First, high-purity titanium sponge or titanium master alloy is prepared as the base material for titanium alloy preparation.
Smelting: The titanium sponge or master alloy is melted under a protective atmosphere or vacuum conditions. Other alloying elements may need to be added during the melting process to achieve the desired alloy composition.
Ingot Preparation: The molten liquid titanium alloy is cast into ingots through a casting process. Ingot processing methods include forging, rolling, extrusion, and drawing.
Plastic Forming: The ingot undergoes plastic processing, such as forging, rolling, and extrusion, to form the desired titanium alloy shape and specifications.
Heat Treatment: Depending on the specific titanium alloy grade and performance requirements, appropriate heat treatments, such as annealing, solution treatment, and aging, are performed to optimize the alloy's microstructure and macroscopic properties.
Surface Treatment: Surface treatments, such as pickling and polishing, are performed on the titanium alloy material to remove surface oxides and impurities and improve surface quality. Quality Inspection: Prepared titanium alloy materials undergo chemical composition analysis, mechanical property testing, and microstructural observation to ensure they meet standard requirements.
Special Processing: Certain titanium alloy grades may require specialized preparation processes, such as superplastic forming, powder metallurgy, and injection molding.
Different titanium alloy grades may differ in their specific chemical composition, heat treatment regime, and processing techniques to meet specific application requirements. For example, TA7 titanium alloy is primarily used for parts such as aircraft engine casings operating below 500°C, while TC25 titanium alloy is a martensitic, α+β, two-phase, heat-resistant titanium alloy with an operating temperature of up to 550°C.
