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 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 place 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, …
