Zusammenfassung:	A METHOD OF PRODUCING POWDER METAL ARTICLES A method of bonding together two or more powdered metal members is provided which comprises forming a first iron base powder metal member having the desired configuration, with the first powder metal base metal member containing a sufficient amount of copper to cause it to expand upon sintering; forming a second iron base powder metal member into a configuration such that it is adapted to engage in an interference fit relationship at least part of the first iron base powder metal member, with the second iron base powder metal member containing a sufficient amount of nickel to cause it to shrink upon sintering; bringing the first iron base powder metal member into contact with the second iron base powder metal member in such a manner that when they are subjected to a sintering treatment the first member expands against the second member which, in turn shrinks against the first member; and heating the so-bonded members at a sintering temperature which is sufficient to cause them to become metallurgically bonded together.
