The Exploration on New Approach of Strengthening and Toughening of Ceramic Materials

It was assumed that the purpose of strengthening and toughening of ceramic materials can be achieved by adopting ceramic grain boundary stress designing to make artificially physical mis-match in ceramic materials, which induces a suitable stress state, as the role of absorption,consumption or transference for applied energy. The experimental results of some systems showed that this assumption is reasonable and feasible, as well as possible to provide a adaptable way for fabricating ceramic materials with lower cost.
