ABSTRACT:
Methods of making sintered parts from a metal powder composition that contains an amide lubricant are provided. The composition comprises an iron-based powder and a lubricant that is the reaction product of a monocarboxylic acid, a dicarboxylic acid, and a diamine. The composition is compacted in a die, preferably at an elevated temperature of up to about 370.degree. C., at conventional compaction pressures, and then sintered according to standard powder-metallurgical techniques.
