Abstract Scope |
Small-volume zirconia ceramics that exhibit highly cyclic shape memory and superelastic properties are of considerable significance for strengthening, toughening, energy damping and micro-actuation applications. In this presentation, various processing methods to synthesize such small-volume ceramic in a form of micro/nano-sized particles are presented, including spray drying, sol-gel processing methods. The key processing science for controlling the particle size distribution, crystal structures (single crystal, oligocrystal or polycrystal) and phases of such small volume ceramics is revealed and strong shape memory and superelastic properties in these particles are discussed. The applications of these engineered particles as a powder compact or fillers to reinforce aluminum or epoxy-based composites are further demonstrated. The perspective and challenges in scaling-up and application of the shape memory ceramic particles are discussed. |
