欢迎各位老师同学光临!

Microstructure is everything in materials because so many properties are profoundly affected by the balance of scale, morphology and porosity. Over the last thirty years investigators have shown the power of the property-microstructure relation that is so central to materials science, and especially important in ceramics.

In this presentation I will present a hierarchy of microstructure control from our own work on bulk structural, electronic and optical ceramics. Seeding, in which a site favorable for epitaxy is provided, will be shown to yield significant control of phase transformations and subsequently sintering to obtain unique materials. Using acicular and tabular seeds I will show how crystallographic orientation can be induced by templated grain growth (TGG) in piezoelectric ceramics like PMN-PT to yield properties near those of single crystals. I will conclude with a discussion about microstructure composites.
