A brazed part includes two or more components that are brazed together and has related method of making. Using a method of locating parts relative to one another, an inter-component gap between the components may be formed. Subsequently, during brazing, flow control features formed along the inter-component gap may then be used to assist in the retention of the braze material between the components during brazing.

The disclosed method provides a way to fabricate a powder metal compact implementing a top fill through one or more of the upper tool members. The top fill step allows for pre-compaction chamber, defined at least in part by at least one of the upper tool members, to be filled with a powder metal after the upper tool member is initially lowered, but before compaction of the powder metal. The manner in which the pre-compaction chamber is filled allows for the formation of complex geometries in powder metal compacts that are not obtainable using conventional lower tool powder transfer motions and further minimizes or avoids unacceptable variations in powder fill to final part ratios across the powder metal compact.
