Static Fatigue of a Sintered Silicon Nitride.
Abstract
The static fatigue resistance of a sintered silicon nitride was assessed at elevated temperature in air. The material was developed for heat engine applications. No difference in ambient or elevated temperature behavior was noted for the injection-molded or slip-cast versions. The material can maintain 150 MPa flexural stress for up to 1000 hours at 1200 C but is susceptible to slow crack growth and creep phenomena at higher stresses. Originator supplied keywords include: Stress rupture; Strength(general). (Author)
