Design of advanced ceramic composites.

摘要

Ceramics with improved fracture resistance are achieved by incorporation of brittle reinforcing phases and phases which exhibit a stress-induced martensitic transformation and by tailoring the matrix microstructure. The optimization of the toughening effects due to each mechanism must rely on knowledge of microstructural and compositional factors. Recent advances in toughening models are used as a basis for designing these systems. 20 refs., 3 figs.
