Abstract
A new sintering process of the porous Cu-Al oxide alloy has benn investigated. The results indicate taht the green sheets of Cu-Al alloys powder made by tape casting process were able to be sintered by the two-step process; firing in the air to oxidize and sinter, and reducing in H2 gas. In the process, final porosity ratio was not affected by sintering temperature. Because a shrinkage due to a sintering reaction was restricted by the aluminum oxides layer which was formed in a powder during the oxidation-reduction process. The reaction model which can explain the sintering process during the reduction, is described.
