Abstract: A method includes powder forging and machining a workpiece that is fractured to divide the workpiece into separate components. In a green form in which the workpiece is formed of compacted powdered metal and has a body that is generally shaped as a parallelepiped with a pair of end faces. The body defines a bore, a pair of V-notches and a pair of channels. The V-notches are formed into the bore parallel to the central axis of the bore and cooperate to define a separation plane. Each of the channels is formed in an associated one of the end faces at a location where the separation plane intersects the end face. During forging, the channels are closed but create a stress riser that aids in directing the fracture when the components are separated from one another.
