Metal matrix composite - Wikipedia
Residual stress MMCs are fabried at elevated temperatures, which is an essential condition for diffusion bonding of the fiber/matrix interface. Later on, when they are cooled down to the aient temperature, residual stresses (RS) are generated in the composite due to the mismatch between the coefficients of the metal matrix and fiber. . The manufacturing RS significantly influence the

OSA | 4H-SiC wafer slicing by using femtosecond laser …
Silicon carbide (SiC) is promising as a key material for power electronics devices owing to its wide bandgap property. Meanwhile, by the convention wire-saw technique, it is difficult to slice off a thin wafer from bulk SiC crystal without reserving space for cutting. In this study, we have achieved exfoliation of 4H-SiC single crystal by the femtosecond laser induced slicing method. By using
Silicon Carbide is special in the way it breaks down. As it breaks down into smaller particles, the media will expose new, sharp edges. Therefore, black silicon carbide can be best used over and over, such as in a rock tuler.
