THE BRITTLE/DUCTILE TRANSITION IN CUBIC STABILIZED ZIRCONIA
Cubic zirconia has a smooth brittle/ductile transition above 800°C at a loading rate of 1·2 × 10-4 MPa m s-1. Pre-stressing at 950°C increases the room temperature fracture toughness in a controllable manner. The toughness increase is caused by dislocation shielding of the crack tip and may be predi...

description | Cubic zirconia has a smooth brittle/ductile transition above 800°C at a loading rate of 1·2 × 10-4 MPa m s-1. Pre-stressing at 950°C increases the room temperature fracture toughness in a controllable manner. The toughness increase is caused by dislocation shielding of the crack tip and may be predicted using a model for dislocation generation by crack tip dislocation sources. © 1994. |
