Tailoring the Plasticity of Topologically Close-Packed Phases via the Crystals' Fundamental Building Blocks.

Brittle topologically close-packed precipitates form in many advanced alloys. Due to their complex structures, little is known about their plasticity. Here, a strategy is presented to understand and tailor the deformability of these complex phases by considering the Nb-Co µ-phase as an archetypal material.
