Summary

The influence of microstructure on the toughening of monophase ceramics by grain bridging is the subject of this paper. The focus is on the role of grain size and shape and of internal residual stresses in the fracture mechanics formulation for the R-curve. Special attention is given to attendant strength properties, particularly flaw tolerance, and to their implications in design. The need for a strong properties-processing link in the fabrication of “monolithic composites” is stressed.
