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
