'Meta-Crystals' Make Materials Tougher and Lighter

A group of UK-based researchers has found a way to create more damage-tolerant architected materials by mimicking the more irregular microscale crystalline structure in strong metal alloys. The breakthrough could give way to materials with entirely new properties such as greater strength, lighter weight, and resistance to damage from material stress. In materials science, mimicking nature in the form of architected materials can often yield improved results such as more strength and...
