摘要：
The room- and high-temperature mechanical properties of a high-strength, sintered silicon carbide were evaluated. Room-temperature strength was measured in four-point bending. The room-temperature fracture toughness was determined using a precracked single-edge-notched beam (SENB) bridge indentation technique. The high-temperature behavior was evaluated using the stepped-temperature stress rupture (STSR) procedure. Both the room- and the high-temperature behavior are superior to those of previously tested commercial sintered alpha and beta silicon carbides.
