Ultra-High-Strength Nanofibrillar Al2O3-YAG-YSZ Eutectics

Ceramic rods consisting of bundles of well‐oriented, single‐crystal whiskers of Al2O3, Y3Al5O12, and ZrO2 (20 mol % Y2O3) are grown by directional solidification from the melt at high growth rates in an inert atmosphere by using the laser‐heated floating zone method. The nanofibrillar eutectic exhib...

Summary:Ceramic rods consisting of bundles of well‐oriented, single‐crystal whiskers of Al2O3, Y3Al5O12, and ZrO2 (20 mol % Y2O3) are grown by directional solidification from the melt at high growth rates in an inert atmosphere by using the laser‐heated floating zone method. The nanofibrillar eutectic exhibits an outstanding bending strength (4.6 GPa) and resistance to crack propagation perpendicular to the fibers. The figure shows a TEM image of a longitudinal cross‐section of the rod.
