A method of manufacturing metal matrix composite (MMC) parts, including the steps of applying a metallic sheath around a bundle of MMC laminates, heating the bundle of MMC laminates in the metallic sheath at a curing or fusing temperature to consolidate the bundle of MMC laminates into a single cured or fused part, and then cooling the cured or fused part. The bundle of MMC laminates may be formed by removing surface contamination from the dry reinforcement fibers, creating a plurality of individual MMC laminates by plating dry reinforcement fibers with electroless nickel, and/or electrodeposited nickel or cobalt, and stacking each of the plurality of individual MMC laminates into a bundle. Autocatalytic and/or electroplating may be used as the primary means to incorporate fiber reinforcement into the metal matrix composite by covering and bonding fiber reinforcement into MMC laminates/plies and/or 3-D woven parts.

A method for fabricating an article includes forming a billet consisting essentially of a stainless steel composition of manganese 2.00 wt. %-24.00 wt. % chromium 19.00 wt. %-30 wt. % molybdenum 0.50 wt. %-4.0 wt. % nitrogen 0.25 wt. %-1.10 wt. % carbon ≤1 wt. % phosphorus ≤0.03 wt. % sulfur ≤1 wt. % nickel <22 wt. % cobalt <0.10 wt. % silicon ≤1 wt. % niobium ≤0.80 wt. % oxygen ≤1 wt. % copper ≤0.25 wt. % balance iron.
The billet is annealed and cold worked to form an article. Without annealing of the article, the article is subsequently case hardened at a single case hardening temperature to form a surface layer on a top surface thereof. Articles formed with the indicated stainless steel composition with case hardened surface layers are also provided.

A general procedure applied to a variety of sol-gel precursors and solvent systems for preparing and controlling homogeneous dispersions of very small particles within each other. Fine homogenous dispersions processed at elevated temperatures and controlled atmospheres make a ceramic powder to be consolidated into a component by standard commercial means: sinter, hot press, hot isostatic pressing (HIP), hot/cold extrusion, spark plasma sinter (SPS), etc.

A deployable manufacturing center (DMC) system includes a foundry module containing a metallurgical system configured to convert a raw material into an alloy powder, and an additive manufacturing (AM) module containing an additive manufacturing system configured to form the alloy powder into metal parts. The deployable manufacturing center (DMC) system can also include a machining module containing a machining system configured to machine the metal parts into machined metal parts, and a quality conformance (QC) module containing an inspection and evaluation system configured to inspect and evaluate the metal parts. A process for manufacturing metal parts includes the steps of providing the deployable manufacturing center (DMC) system; deploying the (DMC) system to a desired location; forming an alloy powder from a raw material using the deployable foundry module; and then forming the metal parts from the alloy powder using the additive manufacturing (AM) module.

The present disclosure is directed and formulations and methods to provide alloys having relative high strength and ductility. The alloys may be provided in seamless tubular form and characterized by their particular alloy chemistries and identifiable crystalline grain size morphology. The alloys are such that they include boride pinning phases. In what is termed a Class 1 Steel the alloys indicate tensile strengths of 700 MPa to 1400 MPa and elongations of 10-70%. Class 2 Steel indicates tensile strengths of 800 MPa to 1800 MPa and elongations of 5-65%. Class 3 Steel indicates tensile strengths of 1000 MPa to 2000 MPa and elongations of 0.5-15%.
