CMCs are a promising candidate material for the next generation aero-engine. SiC/SiC was chosen as the material for application study of turbine nozzle. Fatigue property is important to consider the applicability of CMC parts. So, tensile fatigue tests were conducted for both LCF and HCF region, from 10³ to 10
7 cycles, at elevated temperature up to 1100 degrees Celsius. Fatigue test with notched coupons were also conducted to consider the stress concentration effect. Properties change during the tests and the micro structural observation were investigated. [ABSTRACT FROM AUTHOR]- Published
