Description

Microwave annealing of dense Si3N4-4% Y2O3 materials showed improvements over conventional heating. Increases in fracture toughness and high temperature strength were observed. The high temperature dynamic fatigue showed increased stress to failure for specimens microwave annealed between 1400-1550 degrees C for periods >5 h. 22 refs., 6 figs., 1 tab
