  When a multicomponent liquid composed of particles with random interactions
is slowly cooled below the freezing temperature, the fluid reorganises in order
to increase (decrease) the number of strong (weak) attractive interactions and
solidifies into a microphase-separated structure composed of domains of
strongly and of weakly interacting particles. Using Langevin dynamics
simulations of a model system we find that the limiting tensile strength of
such solids can exceed that of one-component solids.
