Abstract: PURPOSE:To easily produce a compositionally gradient sintered material by heating a homogeneous mixture of the >=2 kinds of powders having different m.p. and sp.gr. at a specified temp., melting the low-m.p. powder to form a liq. phase and forming a gradient composition by gravity. CONSTITUTION:For example, a Cu powder having 1083 deg.C m.p. and 8.6 sp.gr. and a ZrO2 powder having m.p. of 2700 deg.C and 6.1 sp.gr. are uniformly mixed, the mixture is placed in a vessel and subjected to hot isostatic pressing at about 1300 deg.C which is higher than the m.p. of Cu and lower than that of ZrO2, hence the Cu powder is melted into a liq. phase, the liq. phase of Cu descends by gravity, and the Cu/ZrO2 in the ZrO2 is gradually increased downward to form a gradient composition. The mixture as such is sintered, and a compositionally gradient material is extremely easily produced from the raw powders.
