Numerical simulation and experimental research on superplasticity of ceramic matrix laminated composite

In order to investigate the superplasticity of ceramic matrix laminated composite, the superplastic deep-drawing process was simulated by FEM. The results shown that the strain and stress conditions of laminated composite, made by ceramic with different superplastic formability, were better than that of monolithic ceramic. Consequently, the material might had superior superplasticity. Tape casting and hot-press sintering were used to fabricate Al₂O₃/3Y-TZP laminated composite. As-received material was deep-drawing at high temperature to research its superplasticity. The results shown that when suitable strain rate and forming temperature were used, the as-received material had superior superplasticity. This testified the conclusion of FEM simulation.
