Dispersion reinforced systems are composites with a matrix reinforced with a dispersive discontinuous
phase. They are mainly produced by powder metallurgy technologies. Dispersion-strengthened materials have a
polycrystalline matrix, into which dispersed particles are introduced, most often of the type of oxides, carbides
and nitrides. The essence of the strengthening effect of dispersoids is both direct and consists in inhibiting the
movement of dislocations of the matrix, as well as indirect in that, during the formation of the system, dispersoids
increase the density of dislocations and refine the grain and subgrain structure.
