TIMETAL 6-2-4-6 is an alpha-beta alloy capable of being heat treated to higher strengths in greater section sizes than TIMETAL® 6-4 alloy. The properties of this alloy are influenced by its thermo-mechanical history. Enhanced strength, ductility, and low-cycle fatigue properties are contained in alpha-beta forged material. Beta-forged material contains the best combination of good low-cycle fatigue and fatigue-crack growth resistance. TIMETAL 6-2-4-6 alloy is similar in forgeability and crack sensitivity to TIMETAL 6-4. This alloy is used in intermediate compressor stages of turbine engines for disks and blades, seals, and for airframe parts.
