Abstract

We have already innovated superplastically foaming method in which pore expands after densification of the matrix utilizing the superplastic deformation. Based on this superplastically foaming method using 3YSZ (3 mol% yttria stabilized zirconia) and α-SiC as matrix and foam agent, respectively, we have successfully fabricated several dots closed pore pattern and C-shaped as well as S-shaped closed tube patterns by optimizing the amount of matrix 3 YSZ. In addition to the shape of the closed pore, the protuberance based on the expansion of the pore changed with the location of the foam agent in the matrix. The shape of the closed pores and the interaction between them can be controlled by the concentration of the foam agent and the amount of the matrix.
