Abstract

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.
