1. Composition and Microstructure of TC17 Titanium Alloy
TC17 titanium alloy is an α-β two-phase titanium alloy primarily composed of titanium (Ti), aluminum (Al), tin (Sn), zirconium (Zr), manganese (Mn), and chromium (Cr). The precise proportions of these elements within the alloy give TC17 titanium alloy its unique physical and chemical properties.
Titanium, as the main component of the alloy, offers advantages such as low density, high strength, and excellent corrosion resistance. The addition of aluminum not only increases the strength and hardness of titanium alloys but also further reduces their density, making them lighter while maintaining strength. Trace additions of elements such as tin, zirconium, manganese, and chromium significantly impact the microstructure and properties of titanium alloys. By adjusting the ratio of α- and β-phases and refining the grain structure, they significantly improve the alloy's fracture toughness and hardenability.
