A method is provided for fabricating iron castings for metallic components. The method for fabricating the iron castings may include forming a molten solution by melting carbon and iron and combining carbon nanomaterials with the molten solution. A first portion of the carbon nanomaterials combined with the molten solution may be dispersed therein. The method may also include cooling the molten solution to solidify at least a portion of the carbon thereof to fabricate the iron castings. The first portion of the carbon nanomaterials may be dispersed in the iron castings.

Physical property improvement of iron castings using carbon nanomaterials

A method of making a turbomachine part, wherein the method can include machining a blank into a base having blades extending therefrom, the blades defining a channel therebetween. The method can also include forming a bridge constructed from refractory material in the channel between the blades, and forming a cover on the tops of the blades and over the channel, such that the base, the blades, and the cover form a single substantially homogenous turbomachine part once the bridge is removed.
