A method for creating an object by consolidating a powder includes providing a composite including a first material arrange to form a porous structure and a second, sacrificial, material surrounding the first material. The composite may be surrounded with a powder and an intermediate objecting may be formed having a dense part bonded to the composite by densifying and bonding the powder to the composite in a single process. The second material may be removed from the intermediate object to from the object, which may include the porous structure and the dense part bonded to the porous structure.

According to one aspect of the disclosure, a method of manufacturing an implant may comprise manufacturing a first portion, coupling an insert with the first portion to form a combined first portion and insert assembly, and additively manufacturing a second portion on the assembly after the coupling step.

A method of direct printing or writing of a metallic material involves depositing, with a printing device or writing device, an ink comprising of at least undercooled liquid metallic particles dispersed in a carrier fluid. The ink is deposited on any substrate surface to deposit the undercooled liquid metal particles thereon as one or more layers that can form a desired pattern or layered structure.

A first layer of microspheres is dispersed on the first side of the metal matrix material. A second layer of microspheres is dispersed on the second side of the metal matrix material.

A multilayered material system includes at least one of a liner sheet and a cellular core, and a multilayered composite joined to the at least one of a liner sheet and a cellular core. The multilayered composite includes hollow microspheres dispersed within a metallic matrix material.

The present invention is a method for producing a porous metal body or a method for producing an electrode catalyst, which is capable of simplifying the production process and improving the production efficiency by not requiring a step of immersion in an acid treatment solution. A method for producing a porous metal body according to the present invention comprises: a step for forming a metal resin-containing layer, which contains a metal and a resin that has a lower melting point than the metal, on a base; and a step for obtaining a porous metal body by subjecting the metal resin-containing layer to a heat treatment, thereby sintering the metal and removing the resin from the metal resin-containing layer.

This sintered porous silver film is obtained by sintering silver particles, wherein a crystallite size is 60 nm to 150 nm, a ratio of a detected amount of C.sub.3H.sub.7.sup.+ ions to a detected amount of Ag.sup.+ ions which are measured by time-of-flight secondary ion mass spectrometry is 0.10 to 0.35, and a ratio of a detected amount of C.sub.2H.sup. ions to the detected amount of Ag.sup. ions which are measured by time-of-flight secondary ion mass spectrometry is 0.9 to 3.7.

A heat transfer surface with a convective cooling layer includes a metal substrate and a porous metal foam layer transient liquid phase (TLP) bonded on the metal substrate. The porous metal foam layer includes a plurality of high melting temperature (HMT) particles and a plurality of micro-channels. A first TLP intermetallic layer is positioned between, and TLP bonds together, adjacent HMT particles to form the porous metal foam layer. A second TLP intermetallic layer is positioned between and TLP bonds a subset of the plurality of HMT particles to the metal substrate such that the porous metal foam layer is TLP bonded to the metal substrate. The plurality of micro-channels extend from an outer surface of the porous metal foam layer to the metal substrate such that a cooling fluid may be wicked through the plurality of micro-channels to the surface of the metal substrate.
