Verification of Creep Performance of a Ceramic Gas Turbine Blade
Key Engineering Materials
QN a!! mt2 m m llsl W m q p RECEIVED Abstract O S T I Tensile creep tests were carried out on a Norton NT164 silicon nitride ceramic turbine blade containing 4 wt. % Y201 sintering additive at 1370°C in air under selected stress levels. The objective of this study was to measure the creep p r o p e s of test specimens extracted h m a complex shaped ceramic gas turbine blade to veri@ the response of actual components. The creep results indicated that specimens from both the airfoil and dovetaildoi:10.4028/www.scientific.net/kem.161-163.671 fatcat:l7glgurgqjd25g2gzvry54yqla
