摘要： In a method of manufacturing a sheet member comprising: obtaining a sintered compact by sintering a sheet-like compact having a reduced-thickness portion and an enlarged-thickness portion; and then repressing the sintered compact into a sheet member, a difference in density between the reduced-thickness portion and the enlarged-thickness portion of the sintered compact after repressing is adjusted to be in a range of .+-.1.5%. By doing so, the accuracy of flatness is enhanced and the amount of distortion, which would otherwise remain in the sheet member, is reduced because the sheet member is formed by sintering the sheet-like compact. In addition, the deformation caused by heating is greatly restricted. Accordingly, the prospect of the sheet member of the present invention is bright as a heat dissipating plate.

摘要： A plurality of blanks divided at a division end face 5 or a blank-bonded product comprising a plurality of blanks sintered and bonded together are or is compressed in the same mold, so that they are plastically deformed until the division end faces 5 are cohered. Thereafter, a load is applied to the plastically worked product in a direction of breaking of the division end faces 5 to break the division end faces 5 and divide the plastically worked product into a plurality of members. In this manner, a split type mechanical part having irregularities meshed with each other on mating faces and easily positionable relative to each other can be produced with a good dimentional accuracy.

摘要： There is provided a connecting rod including a connecting rod body and a cap having excellent alignment properties, and a method of producing such a connecting rod. A connecting rod body and a cap are produced through the steps of molding green compacts respectively corresponding to the connecting rod body and the cap; sintering and unifying both the green compacts; forging the resultant sintered product in a mold; and fracturing the resultant forged product. The green compact corresponding to the cap and/or the green compact corresponding to the connecting rod body includes opposite circumferential end faces formed with one or more projection. A clearance c is formed between both circumferential end faces of the sintered product due to the projection. With this clearance c, both the circumferential end faces are formed with recesses and projections which are fitted to each other during the forging process and which are relatively large and thus have large biting amounts. During the fracturing process, the recesses and the projections are separated into two pieces.
