Aluminum-cerium-manganese alloy embodiments for metal additive manufacturing

A method for preparing metal/metal interpenetrating phase composites is provided. The method includes forming a preform using additive manufacturing. The preform defines a materially continuous three-dimensional open-cell mesh structure. The preform includes a first metal having a melting point. The method further includes pre-heating the preform to a first temperature less than the melting point of the first metal. The method includes infiltrating the preform with a second metal in liquid form. The second metal has a melting point lower than the melting point of the first metal. The method also includes allowing the second metal to cool and form a solid matrix. The solid matrix defines a continuous material network.

Additive manufactured interpenetrating phase composite

The present disclosure concerns embodiments of aluminum alloy compositions exhibiting superior microstructural stability and strength at high temperatures. The disclosed aluminum alloy compositions comprise particular combinations of components that contribute the ability of the alloys to exhibit improved microstructural stability and hot tearing resistance as compared to conventional alloys. Also disclosed herein are embodiments of methods of making and using the alloys.

Aluminum alloy compositions and methods of making and using the same

The present disclosure concerns embodiments of aluminum alloy compositions exhibiting microstructural stability and strength at high temperatures. The disclosed aluminum alloy compositions comprise particular combinations of components that contribute the ability of the compositions to exhibit improved microstructural stability and hot tearing resistance as compared to conventional alloys. Also disclosed herein are embodiments of methods of making and using the alloys.

Disclosed herein are embodiments of an aging heat treatment that can be used to replace conventional aging steps when making alloy embodiments of the present disclosure. Embodiments of the disclosed aging heat treatment reduce cost and complexity in producing aluminum alloy-based components while also promoting and/or improving microstructure stability of the aluminum alloys.

Heat treatments for high temperature cast aluminum alloys

A seal for a solid oxide fuel cell includes a glass matrix having glass percolation therethrough and having a glass transition temperature below 650&#xb0; C. A deformable second phase material is dispersed in the glass matrix. The second phase material can be a compliant material. The second phase material can be a crushable material. A solid oxide fuel cell, a precursor for forming a seal for a solid oxide fuel cell, and a method of making a seal for a solid oxide fuel cell are also disclosed.

Engineered glass seals for solid-oxide fuel cells

An apparatus, system, and method are disclosed for detecting cracking in a particulate filter. The method may include providing an apparatus comprising an aftertreatment device with a substrate and a substrate surface, a conductive material forming a conduction path bonded to the surface of the substrate surface, and access points configured to allow a resistance measurement of the conduction path. The method may include measuring the resistance of the conduction path, and determining if one or more cracks have occurred on the substrate surface based on the resistance measurement. The method may further include labeling the degradation level of the aftertreatment device based on the indicated amount of cracking, and replacing the aftertreatment device with an equivalent aftertreatment device, based on the degradation level, after a service event.
