Summary

This study investigated the influence of growth conditions on the microstructure and mechanical behavior of fibers of aluminum oxide, A12O3, and zirconium oxide, ZrO2, eutectic grown by the Edge defined-Film fed-Growth (EFG) method. The results indicated a dependence of microstructure on growth rate, with no strong correlation to other growth parameters. Room temperature bend and tensile strengths showed little correlation to microstructure or growth rate. Some evidence indicated higher strengths related to tungsten dies. Air annealing increased strengths by about 20% over as-grown values. The room temperature strengths of as-grown fibers measured in this work (overall average of 1.37 GPa, (199,000 psi)) exceed those measured in all previously published studies of this system.
