Effect of liquid state organization on microstructure and strength of model multicomponent solids
arXiv:1903.05959 · doi:10.1103/PhysRevLett.123.035502
Abstract
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.
