Popis: Quasicrystals are typically stiff and hard, but also brittle in bulk form at room temperature. Here, authors observe ductile behaviour in quasicrystalline pillars of submicron diameter and provide evidence for dislocation-based plasticity at intermediate length scales and room temperature as an explanation.
