# Effect of liquid state organization on microstructure and strength of model multicomponent solids

## TL;DR

This study uses simulations to show that multicomponent solids formed from liquids with specific interaction patterns can have higher tensile strength than single-component solids, depending on their microstructure.

## Contribution

It reveals how liquid state organization influences microstructure and enhances the tensile strength of multicomponent solids, a novel insight into material design.

## Key findings

- Microphase-separated structures form during slow cooling.
- Tensile strength can surpass that of one-component solids.
- Microstructure depends on interaction strength distribution.

## 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.
