  • Method of manufacturing a powder metal connecting rod with stress riser crease formed in the side face
    Patent number: 5613182
    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.

  • Forged powder metal connecting rod with stress riser crease formed in side thrust face
    Patent number: 5594187
    Abstract: This invention relates to an apertured connecting rod having a stress riser crease formed in one side thrust surface made by forging a powder metal sintered preform with a V-shaped notch mold formed in a side face whereby the spaced surfaces defining the V-shaped notch are folded inwardly toward one another during the forging to create a deep crease without any substantial width.

  • Method of producing high density iron-base material
    Patent number: 4155754
    Abstract: A method of producing a high density iron-base material by a powdered metal process includes blending powder of a substantially eutectic alloy with carbon particles to increase the difference between the solidus and liquidus temperatures of the blend. The blend is then compacted and sintered at a temperature between the solidus and liquidus temperatures to achieve the desired high density.
