A composite material comprising a metal matrix and nanocellulose supplement. The metal matrix is formed of a metal base material and may be monolithic throughout the composite material. The nanocellulose supplement improves a material property of the metal matrix and is formed of a nanocellulose supplement material dispersed in the metal base material. Importantly, the nanocellulose supplement material does not become damaged when the composite material is formed.

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 disclosure relates to a method for preparing Ti(C,N)-based superhard metal composite materials, with Ti(C,N) powder and (W,Mo,Ta)(C,N) powder as main raw materials and Co powder as binding phase for preparation, thereby obtaining a material in which a microstructure is a double-core rim structure that has both a black core rim and a white core rim. The material has a complete and evenly distributed double-core rim structure. In the condition that the ensured hardness of the material is not reduced and even slightly increased, the toughness of the material is significantly improved, wherein the fracture toughness of the material is in the range of 11.3 to 12.5 MPa.Math.m.sup.1/2.

A method for forming a caloric regenerator includes depositing layers of additive material. The additive material includes a caloric material. The method also includes joining the layers of additive material to one another. After joining the layers of additive material, the caloric regenerator includes a regenerator body that extends longitudinally between a hot end portion and a cold end portion. A working fluid is flowable through the regenerator body between the hot and cold end portions of the regenerator body. The layers of additive material are deposited such that one or more of a cross-sectional area of the regenerator body, a void fraction of the regenerator body, a characteristic size of the caloric material, and a composition of the caloric material varies along a length of the regenerator body between the hot and cold end portions of the regenerator body.

In one aspect, methods of making freestanding metal matrix composite articles and alloy articles are described. A method of making a freestanding composite article described herein comprises disposing over a surface of the temporary substrate a layered assembly comprising a layer of infiltration metal or alloy and a hard particle layer formed of a flexible sheet comprising organic binder and the hard particles. The layered assembly is heated to infiltrate the hard particle layer with metal or alloy providing a metal matrix composite, and the metal matrix composite is separated from the temporary substrate. Further, a method of making a freestanding alloy article described herein comprises disposing over the surface of a temporary substrate a flexible sheet comprising organic binder and powder alloy and heating the sheet to provide a sintered alloy article. The sintered alloy article is then separated from the temporary substrate.
