TC11 powder
TC11 powder
TC11 (Ti-6.5Al-3.5Mo-1.5Zr-0.3Si) is a near-alpha high-temperature titanium alloy independently developed and widely used in China. It combines excellent high-temperature strength, creep resistance, fatigue resistance, and good thermal stability, making it one of the important structural materials for key hot-end components of aero engines.The strengthening mechanism of TC11 alloy mainly comes from the solid solution strengthening effect of Al element and the stabilization effect of Mo element on the β phase. Additionally, the addition of a small amount of Si element can effectively improve the high-temperature creep resistance and thermal stability of the material. Therefore, TC11 can maintain high strength and good structural stability under high-temperature environments.
