Abstract

PURPOSE: To obtain superior mechanical strength without resintering, by subjecting the powdery compact made of steel containing a prescribed amount of an easily oxidizable alloy element to vacuum sintering and by performing hot forging at a prescribed temperature.
CONSTITUTION: Powder of steel containing 0.8W10wt% one or more kinds of easily oxidizable alloy elements selected among Mn, Cr, Si, and V is compacted. This powder is sintered at 1,200°C for 30min in 10-3Torr vacuum, thereafter hot forging is carried out in an atmosphere of inert gas at 900W1,200°C. This method accelerates the sintering remarkably, increases binding strength and reduces internal inclusions, suppressing the occurrence of microcracking. Therefore, superior mechanical strength is obtained even when resintering is not carried out after the forging.
