Research output: Chapter in Book/Report/Conference proceedingConference contribution


Improvement of the drop in shrinkage rate of metal/ceramic powder mixtures may be important to avoid defects, such as distortion or cracking, in sintering of functionally graded materials. The authors previously proposed a method of increasing the sinterability of metal/ceramic powder mixtures by inhomogenization of microstructure, which was achieved by granulating ceramic and metal powders separately before compaction. In this study, Ni/Al 2O3 graded powder compacts are prepared with the inhomogeneous mixtures on some conditions, and the sintering behavior of the compacts is examined analytically and experimentally. Consequently, the effects of inhomogenization on suppressing the sintering defects in graded layers are confirmed.
