Ti-6Al-2Sn-4Zr-2Mo is a near-alpha titanium alloy designed for high-temperature service up to 540°C — approximately 100°C higher than Ti-6Al-4V's maximum operating temperature. It is used for compressor discs and blades in the hot section of jet...
Ti-6Al-2Sn-4Zr-2Mo ist ein near-alpha titanium alloy designed für hoch-temperature service auf zu 540°C — approximately 100°C higher als Ti-6Al-4V's maximum operating temperature. Es ist used für compressor discs und blades in der heiß abschnitt von jet engines, wo creep widerstand bei elevated temperature ist der design-limiting criterion.

Frequently Asked Questions
Warum nicht gerade verwenden Ti-6Al-4V für hoch-temperature aerospace teile?
Ti-6Al-4V loses strength rapidly über 350°C und hat limited creep widerstand über 400°C due zu sein alpha-beta microstructure. Ti-6242's near-alpha structure (mit tin, zirconium, und molybdenum stabilizing der alpha phase) maintains strength und creep widerstand zu 540°C.
