Welding using metal-ceramic composites
TLDR
In this article, a method for welding metal composite materials, including metal-ceramic composites, whereby a weld or filler material is prepared by the in-situ precipitation of ceramic in a metallic matrix is described.Abstract:
A method for welding metal composite materials, including metal-ceramic composites, whereby a weld or filler material is prepared by the in-situ precipitation of ceramic in a metallic matrix The filler material may comprise boride, carbide, oxide, nitride, silicide, etc, while the matrix metal may constitute a alloy or intermetallic of two or more metals A strong bond is achieved when welding two conventional metals, a conventional metal and a metal-ceramic composite, or two metal-ceramic compositesread more

Arc-melting process for forming metallic-second phase composites
TL;DR: In this paper, an arc-melting method is used for the formation of metallic second phase composite materials, where the intermediate material is then combined with an additional amount of metal and arcmelted to form a final composite comprising a lower loading of the second phase particles dispersed in a final metallic matrix.

Metal articles having a plurality of ultrafine particles dispersed therein
TL;DR: In this article, a process for the electroless plating of easily reducible metals onto ultrafine, usually inert, particles is described. But the plating is achieved through careful and accurate control of such parameters as the feed rates of the various solutions, the control of pH of the solution, the temperature, pressure and the rate of agitation in which the solution is taking place.

Diffusion bonding of superalloy members
Abstract: An improved diffusion-bonded, age hardenable joint between superalloy members results from a method which combines the benefits of vacuum high-temperature brazing and pressure solid-state diffusion bonding through use of an age hardenable bonding powder related to the superalloy and including temperature depressants selected from B, Si, Mn, Cb, Ta and their mixtures. The method avoids the need for pressure during the diffusion bonding portion.
