摘要： The present invention provides a method of making metallurgical powder compositions and a method of using the metallurgical powder compositions produced. The method of the present invention includes providing a prealloy powder containing iron and one or more alloying additives that is preferably molybdenum, and admixing the iron-based prealloy powder with a copper containing powder having a weight average particle size of 60 microns or less, and a nickel containing powder having a weight average particle size of 20 microns. The mixture containing the iron-based prealloy powder, copper containing powder, and nickel containing powder is bonded in some manner to facilitate adhesion of the prealloy powder with the other alloying powders. Preferably, a binding agent is used to effect bonding. The metallurgical powder compositions thus produced have, for example, improved mechanical strength properties when formed into metal parts.

摘要： An improved metallurgical powder composition comprising an iron-based powder and an alloying powder is provided. The composition contains a polyalkylene oxide having a number average molecular weight of at least about 7,000 as a binder. The binder of this invention permits the bonded powder composition to achieve compressibility equivalent to that of unbonded compositions and maintains resistance to dusting and segregation of the alloying powder.

摘要： The present invention provides iron-based infiltration methods for manufacturing powder metallurgy components, compositions prepared from those methods, and methods of designing those infiltration methods. Iron-based infiltration methods table include the steps of providing an iron-based infiltrant composed of a near eutectic liquidus composition of a first iron based alloy system and an iron-based base compact composed of a near eutectic solidus powder composition of a second iron based alloy system. The base compact is placed in contact with the infiltrant and heated to a process temperature above the melting point of the infiltrant to form a liquid component of the infiltrant. Lastly, the base compact is infiltrated with the liquid component of the infiltrant. During infiltration, the liquid component of the infiltrant flows into the pores of the base compact.
