Processing Defects and Nanoindentation Mechanical Properties in Tape Cast Alumina/Zirconia/Mullite Layered Composites
Symmetric three-layer alumina/zirconia/mullite composites have been prepared by tape casting and hot-pressing (20 MPa) at 1500°C for 2 h in argon. The hardness and Young’s modulus of the layered materials were evaluated using low load continuous depth-sensing indentation equipment (nanoindentation), appear to be affected by the formation of processing defects and residual stress.
