A method for producing a green body for a machining segment, where the machining segment is connectable to a basic body of a machining tool by an underside of the machining segment, includes placing first hard material particles in a matrix material in a defined particle pattern. The first hard material particles are placed in the matrix material with a respective projection with respect to the matrix material.

A method of preparing a substrate having a wetting surface, including confirming the presence of an open, interconnected pore network in a ceramic substrate to be wetted with a first metal, filling the open, interconnected pore network with a second metal,

exuding the second metal to coat the surface of the substrate, and wetting the substrate with the first metal. The ceramic substrate is not decomposed by the first metal and the ceramic substrate is not decomposed by the second metal.

Provided are an aluminum alloy having an adjusted microstructure in an aluminum matrix or an aluminum alloy matrix for high elongation percentage or high strength and a method of fabricating the same. The aluminum alloy includes an aluminum-based matrix; and a nonmetal element solidified in the aluminum-based matrix, wherein stacking fault energy of the aluminum alloy is decreased compared to that of pure aluminum.

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.

A method of forming a component includes mixing a powdered base material and a binder to define a mixture, forming the mixture into a desired shape without melting the base material, removing the binder from the desired shape to define a skeleton, the volume of the skeleton being between 80 percent and 95 percent base material, and infiltrating the skeleton with a melting point depressant material to define a finished component, the finished component having less than one percent porosity by volume.
