The disclosure describes assemblies, systems, and techniques for reinforcing complex geometries of pressure vessels using a pre-sintered preform (PSP) braze material that includes a low-melt powder and a high-melt powder. An example technique includes positioning a PSP reinforcement on a surface of a substrate. The technique includes heating the PSP reinforcement to soften or melt at least one constituent metal or alloy of the low-melt powder. During heating, the PSP reinforcement is configured to conform to a contour of the surface of the substrate. The technique also includes cooling the PSP reinforcement to define a reinforced component.

The invention relates to a stainless steel blank for making a Damascus patterned article, wherein the steel blank is made from at least two different nitrogen alloyed stainless steels having a chromium content of 11-25 weight %, of which at least one of the steels comprises nitrogen in an amount of 0.10-5.0 weight % and, optionally, at least one of the steels comprises nitrogen in an amount of 0.01-0.5 weight %.

The invention aims to provide a contactless method to create small conductive tracks on a substrate. To this end a method is provided for selective material deposition, comprising depositing a first material on a substrate; followed by solidifying the first material selectively in a first solidified pattern by one or more energy beams; and followed by propelling non-solidified material away from the substrate by a large area photonic exposure, controlled in timing, energy and intensity to leave the solidified first pattern of the first material.

This application relates to a method of manufacturing a metal-polymer composite material having high thermal conductivity and electrical insulating properties. The method may include preparing a powder mixture comprising polymer powder and metal powder, and spark plasma sintering (SPS) the powder mixture to produce a composite material.

Inventive techniques for forming unique compositions of matter are disclosed, as well as various advantageous physical characteristics, and associated properties of the resultant materials. In particular, particles comprising polymer matrices are characterized by having carbon disposed within the polymer matrix structure thereof. The carbon is primarily, or entirely, present at interstitial sites of the polymer matrix, and may be present in amounts ranging from about 15 wt % to about 90 wt %. The carbon, moreover, forms covalent bonds with both atoms of the polymer matrix and other carbon atoms present in, but not part of, the matrix. This facilitates substantially homogeneous dispersal of the carbon throughout the resultant material, conveying unique and advantageous properties such as strength-to-weight ratio, density, mechanical toughness, sheer strength, flex strength, hardness, anti-corrosiveness, electrical and/or thermal conductivity, etc. as described herein. In some approaches, the resultant materials may be powderized or pelletized.

Provided are materials that include one or more metals in solid solution with a level of nitrogen that is at a concentration higher than the a solubility limit of nitrogen in the alloy in a liquid state at atmospheric pressure. The materials may be utilized as a protective layer on a substrate, such as an Al containing substrate. Also provided are methods of forming the solid solution materials and articles employing them on a surface of a substrate.
