Alloy compositions for 3D metal printing procedures which provide metallic parts with high hardness, tensile strengths, yield strengths, and elongation. The alloys include Fe, Cr and Mo and at least three or more elements selected from C, Ni, Cu, Nb, Si and N. As built parts indicate a tensile strength of at least 1000 MPa, yield strength of at least 640 MPa, elongation of at least 3.0% and hardness (HV) of at least 375.

3D printable hard ferrous metallic alloys for powder bed fusion

Metallic alloys and methods for the preparation of free-standing metallic materials in a layerwise manner. The resulting layerwise construction provides a metallic skeleton of selected porosity which may be infiltrated with a second metal to provide a free-standing material that has a volume loss of less than or equal to 130 mmas measured according to ASTM G65-04 (2010).

Infiltrated ferrous materials

The present invention relates to alloy compositions for 3D metal printing procedures which provide metallic parts with high hardness, tensile strengths, yield strengths, and elongation. The alloys include Fe, Cr and Mo and at least three or more elements selected from C, Ni, Cu, Nb, Si and N. Ni may be replaced with Mn. As built parts indicate a tensile strength of at least 1000 MPa, yield strength of at least 640 MPa, elongation of at least 3.0% and hardness (HV) of at least 375.

The present disclosure is directed at alloys and method for layer-by-layer deposition of metallic alloys on a substrate to produce a metallic part. Applications for the metallic parts include pumps, pump parts, valves, molds, bearings, cutting tools, filters or screens.

Layered construction of in-situ metal matrix composites

The present disclosure is directed at alloys and method for layer-by-layer deposition of metallic alloys on a substrate. The resulting deposition provides for relatively high hardness metallic parts with associated wear resistance. Applications for the metallic parts include pumps, valves and/or bearings.
