Titanium 10-2-3 is a near beta alloy and has been developed for high strength and corrosion resistance applications. It is used in forgings, valves, pumps, and heat exchangers. The material is also used for tanks, piping, and other industrial equipment.
Forgings made from this alloy offer excellent corrosion resistance and damage tolerance. It is suitable for both isothermal and hot die forging. This alloy can be processed and heat treated, and is ideal for aerospace and automotive components.
In the manufacturing of aerospace titanium alloy components, multiple heat treatments are necessary to achieve desired microstructure. The a” phase dominates the surface region, while the b phase dominates the interior. X-ray diffraction (XRD) patterns and optical microscopy were used to characterize the microstructure of solution-treated Ti-10-2-3 specimens.
Optical micrographs of the surface of the specimens show equiaxed morphologies and martensite plates. The b phase is present in the interior, but it is not visible on the surface. A” and b grain boundaries are preferential sites for martensite formation. Moreover, the microstructure of the a” phase increases with depth of corrosion.
The microstructure of the alloy is influenced by oxygen and heat treatment. It is best to avoid using it in an atmosphere with high levels of oxygen. Furthermore, it is recommended to use cobalt type high-speed tools. Other practices include slow speeds, high feed rates, and high coolant flow.
Ti-10V-2Fe-3Al has excellent corrosion resistance and fracture toughness. It is widely used in forgings, airframe forging, and other aerospace applications.
