ABSTRACT:
This invention relates to a method of manufacturing a connecting rod of powder metal and having a stress riser crease formed on a side thrust face of the rod formed by hot forging a sintered powder metal preform which has a generally V-shaped notch molded in a side surface whereby the hot forging folds the spaced surfaces of the notch towards one another in non-bonding close relation to form a deep, almost widthless crease.
