Paraffin-Based Process for Producing Layered Composites with Cellular Microstructures

A paraffin-based process that results in high-strength bimaterial ceramic layered composites is reported. The process facilitates rolling, folding, and shape retention at room temperature and allows the transition from a laminar to a cellular microstructure during deformation. The strength of sintered alumina/zirconia/alumina composites reached 700 MPa, higher than that of conventional zirconia-toughened alumina composites containing dispersed particles.
