| Abstract Scope |
Ceramics have wide spread industrial applications as structural materials. However, in contrast to metallics materials, most ceramics are brittle at room temperature. The limited plasticity in ceramics is related to extrinsic factors, such as porosity and cracks introduced during processing. Several intrinsic characteristics of ceramics also deprive their plastic deformability. In this presentation, I will give a few examples where processing techniques can be crucial to introduce plasticity in ceramics. For example, field assisted processing methods can be an important means to improve plasticity in ceramics. In addition, recent studies have shown promising techniques to accommodate dislocation induced plasticity in various ceramic materials. The implications of these findings will be discussed for the development of future ceramics with improved plasticity. |
