TIMETAL~R 6-2-4-6 (Alpha-Beta Titanium Alloy)

摘要

Timetal 6-2-4-6 is an alpha-beta alloy with greater strength in thicker sections than Timetal 6-4 (See Alloy Digest Ti-129). Timetal is a registered trademark of Timet, Titanium Metals Corporation. 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 thermomechanical history. Enhanced strength, ductility, and low-cycle fatigue properties are contained in alpha-beta forged material. Beta-forged material also 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.
