Mechanical Property Evaluation at Elevated Temperatures of Sintered Beta Silicon Carbide.

Abstract

Silicon-based ceramics have considerable potential for structural applications in heat engines and other energy conversion devices. This study is part of an ongoing Department of Energy project to screen new materials for their mechanical properties for heat engine applications. A program was carried out to evaluate the mechanical properties at room and elevated temperatures of the General Electric sintered beta silicon carbide. The testing included room temperature flexural strength, flexural stress rupture at 1200 C, and stepped temperature stress-rupture (STSR) experiments. Fractographic examination identified the flaw populations that limited strength. The properties measured on this material are typical of sintered silicon carbide. Keywords: Microhardness.
