Methods for manufacturing a metal foam and a metal foam reinforced back plate may be used to provide high-strength and low weight structural elements in portable information handling systems. A method for manufacturing a metal foam may include selectively adding iridium oxide and ceramic particulate to a light-metal allow to create desired mechanical properties of the metal foam.

Disclosed herein, in certain embodiments, are composite materials, methods, tools and abrasive materials comprising a tungsten-based metal composition, a tungsten carbide, and an alloy. In some cases, the composite materials or matrix are resistant to oxidation.

A friction material having 40 mass % or more to 80 mass % or less of a matrix of at least one of a metal, an alloy, a metal compound and an intermetallic compound; 5 mass % or more to 30 mass % or less of solid particles of at least one of a carbide, a nitride, an oxide and a sulfide; and 5 mass % or more to 40 mass % or less of a lubricant wherein: the matrix comprises, as elements, at least, 20 mass % or more to 50 mass % or less of Fe, 0.05 mass % or more to 5.0 mass % or less of P, and 40 mass % or more to 75 mass % or less of Ni, based on a total amount of the matrix; and a content of Cu as an element is 15 mass % or less based on a total amount of the matrix.

Ternary chromium-molybdenum-aluminum (CrMoAl) alloys that form oxidation-resistant surface films for high-temperature applications are provided. Also provided are methods for thermally pre-treating the alloys to form the oxidation resistant surface films. The surface films have a stratified structure that includes an exterior surface oxide layer comprising chromium oxides and aluminum oxides and an interior aluminum nitride-rich region comprising aluminum nitride precipitates dispersed in a CrMoAl alloy matrix. The interior aluminum nitride precipitates act as oxygen sinks to sequester oxygen diffusing inward into the CrMoAl to prevent further oxidation of the underlying bulk alloy.

A method for manufacturing a machine component made of metal-based material is described. The method comprises the steps of: providing a powder blend comprising at least one metal-containing powder material and at least one strengthening dispersor in powder form, wherein the strengthening dispersor in powder form has an average grain size less than an average grain size of the metal-containing powder material; and forming the machine component by an additive manufacturing process using the powder blend.

Embodiments of a method for producing powder mixtures having uniform dispersion of ceramic particles within larger superalloy particles are provided, as are embodiments of superalloy powder mixtures. In one embodiment, the method includes producing an initial powder mixture comprising ceramic particles mixed with superalloy mother particles having an average diameter larger than the average diameter of the ceramic particles. The initial powder mixture is formed into a consumable solid body. At least a portion of the consumable solid body is gradually melted, while the consumable solid body is rotated at a rate of speed sufficient to cast-off a uniformly dispersed powder mixture in which the ceramic particles are embedded within the superalloy mother particles.

The present disclosure provides a composite heat-dissipation substrate and a method of manufacturing the same. The composite heat-dissipation substrate includes a first ceramic layer having insulating properties, a second porous ceramic layer and a metal layer, wherein the first ceramic layer and the second ceramic layer are continuously connected to each other so as not to form an interface therebetween, and the metal layer is infiltrated into plural pores of the second ceramic layer to be coupled to the ceramic layers, whereby interfacial coupling force between the ceramic layers and the metal layer is very high, thereby providing significantly improved heat dissipation characteristics.

A part includes a three-dimensional porous metallic workpiece printed via an additive manufacturing process and subsequently subjected to a diffusion-based process to convert at least a portion of the porous metallic workpiece to a ceramic workpiece or an intermetallic workpiece.
