Abstract: A method for producing a ceramic matrix composite (CMC) material includes impregnating a set of ceramic fibers with a non-fibrous ceramic material, resulting in a precursor matrix, stabilizing the precursor matrix, resulting in a stabilized matrix, and densifying the stabilized matrix using a frequency assisted sintering technology (FAST) process, resulting in a densified CMC material. The resulting densified CMC exhibits superior strength and toughness, relative to prior CMCs.

Abstract: Methods of forming a polycrystalline table may involve disposing a plurality of particles comprising a superabrasive material, a substrate comprising a hard material, and a catalyst material in a mold. The plurality of particles may be partially sintered in the presence of the catalyst material to form a brown polycrystalline table having a first permeability attached to an end of the substrate. The substrate may be removed from the brown polycrystalline table and catalyst material may be removed from the brown polycrystalline table. The brown polycrystalline table may then be fully sintered to form a polycrystalline table having a reduced, second permeability. Intermediate structures formed during a process of attaching a polycrystalline table to a substrate may include a substantially fully leached brown polycrystalline table. The substantially fully leached brown polycrystalline table may include a plurality of interbonded grains of a superabrasive material.

Abstract: An industrial process for the manufacture of carbon electrodes (artefacts) comprises the steps of(a) mixing a high melting pitch with a Softening Point Mettler (SPM) above 150° C. with carbonaceous solids at a temperature of 50° C. to 120° C. above the SPM of the pitch, pressing or compacting by vibration or extrusion without intentional cooling at a temperature close to the mixing temperature,(b) transferring the artefacts to a carbonization furnace without intentional cooling,(c) carbonizing the artefacts, said process does not need to cool the pitch/coke paste after mixing and/or the green electrode after forming, thus, the heat trapped in the green electrode can be conserved and reduces the total energy consumption and residence time in a subsequent carbonisation step.
