Editing Metal matrix composite (section)

== Residual stress ==
MMCs are fabricated 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 ambient temperature, [[Residual stress|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 mechanical behavior of the MMCs in all loading conditions. In some cases, thermal RS are high enough to initiate plastic deformation within the matrix during the manufacturing process.<ref>{{Cite book|title=Residual Stresses in Composite Materials|last1=Aghdam|first1=M.
