Abstract

PURPOSE:To produce a sintered alloy member having high strength in corner parts by sintering or presintering a compact consisting of raw material powder, then coining the compact to a final corner shape at the time of producing the sintered parts having the corner parts. CONSTITUTION:The corner parts 5 are formed to the shape of 2.0 R larger than 0.5 R of the final product in the stage of subjecting the raw material powder to compacting at the time of producing the sintered parts 4 of the shape having the many corner parts 5 by a powder metallurgical method. After this compact is presintered, the compact is recompressed by coining to the final shape of 0.5 R in the corner parts and is subjected to regular sintering; finally, the size setting of the sintered parts 4 is executed by sizing as needed. The sintered member 4 which has the high strength in the corner parts 5 and extremely minimizes the generation of breakage in the corner parts is obtd.
