Abstract

PURPOSE: To enable the sintered parts of complicated shape to be prepared simply, by dividing the green compact to plural parts being able to be deteched from the mold and by making the respective concave and convex parts for fitting to each other unit fimly with each other owing to the difference of the coefficient of expansion or contraction at the sintering.
CONSTITUTION: In the first place, the parts 1 are divided to 4 pieces AWD and are kept to be albe to be deteched from the mold for molding. At the divided faces of the divided parts A and B, the concave part 4 and the convex part 5 are formed to the shape and dimensions being able to be fitted to each other and other divided parts BWD have the similar concave and convex parts. Besides,each of the divided parts AWD are molded by changing the components and compounding ratios of the metal powders to be the material or by changing appropriately the pressure at the compression molding so that the adjoining mutual parts may generate the difference in the coefficient of expansion or contraction. After the above divided par AWD have been assembled to the shape of the parts 1 by fitting together respective concave and convex parts, by sintering the above assembled parts by heating in the atmosphere of H2 gas, etc., the parts 1 which have been united firmly, are obtained
