摘要: The present invention is directed to methods of preparing a bonded metallurgical powder composition comprising melting a binding agent and blending the melted binding agent with a metallurgical powder mixture, in the substantial absence of solvent, for a time sufficient to form the bonded metallurgical powder composition. Bonded metallurgical powder compositions prepared using these methods are also described, as well as compacted powder metallurgical parts prepared using them.
