Tensile strength data generated in Norton's Ceramic Technology Program (CTP) Processing for Reliability Project is presented for a hot isostatically pressed (HIP'ed) 4 wt% yttria-silicon nitride (designation NCX-5102). This database represents the result of an extensive multi-variable experimental matrix designed to identify an optimized process directed at eliminating or minimizing critical flaws. The strength data follow from room temperature fast fracture tests of net-shaped-formed, pressure cast cylindrical buttonhead tensile bars. Results of over one hundred tensile tests coupled with detailed fractography are summarized using Weibull statistics including competing risk analyses. Specimen fabrication and mechanical testing issues (e.g. machining, strain gaging) which were addressed to ensure the integrity of the strength database will also be discussed.
