SiAlON Ceramics for the High Temperature Applications: High Temperature Creep Behavior

Alper Uludag and Dilek Turan
Abstract—Gas turbine engines have been widely used in electricity power generation in industry and aviation. The performance of gas turbine engines is limited by the temperature and strength capabilities of the materials used in the engine. Silicon nitride based ceramics have been expected to be candidates for gas turbine engine components due to their promising mechanical properties at high temperatures. On this basis, over the last 40 years large number of programs in the world has been working to produce ceramic components for gas turbines with the goals of increasing efficiency and lowering emissions. But there are some difficulties that limit the use of structural ceramics based silicon nitride in gas turbine components. Creep performance is one of those problems and creep performance of a material is one of the major factors for determining its high temperature application. In this study creep behavior of SiAlON ceramics, which are solid solutions of silicon nitride ceramics, were investigated at temperatures from 1100 ˚C to 1400 ˚C under stresses from 50 to 150 MPa in air.

Index Terms—Advanced ceramics, creep, gas turbine engines, high temperature failures, SiAlON.
