Abstract
A method is provided for producing a high strength iron based component by powder metallurgical techniques but without sintering. A powder composition of iron-based particles coated or admixed with a thermoplastic material is compacted under heat and pressure by traditional powder metallurgical techniques. The pressed component is then heat treated at a temperature above the glass transition temperature of the thermoplastic material for a time sufficient to bring the component to the heat treatment process temperature. The resulting component has increased strength and can be used as a structural component or as a magnetic core component.
