Elevated-Temperature R-Curve Behavior of a Polycrystalline Alumina

The fracture behavior of a polycrystalline alumina was examined at temperatures ranging from ambient through 1400°C, using three‐point bend bar test specimens. R‐curves were determined at all temperatures studied, and when accompanied by renotching procedures, a wake removal technique, conclusive ev...
