Metastable Grain Boundary Configurations for Ultrahigh Strength Nanoceramics

Abstract

(Goal #1) to develop synthetic and processing techniques capable of producing ceramic parts with grain sizes in the nanoscale regime (targeting sizes below 10nm);(Goal #2) utilize the obtained products to explore mechanical properties of nanoceramics, enabling development of fundamental understanding on size induced effects on, particularly, hardness and toughness;(Goal #3) based on the developed knowledge, understand and propose mechanisms to increase toughness and hardness of nanocrystalline ceramics.(Goal #4) Train graduate and undergraduate students on contemporary issues of nanoceramic processing, testing and microstructural characterization.
