Here we use phase field to model and simulate “hopper” crystals, so named because of their
underlying cubic structure but with a hopper-like depression on each of the six faces. Over …

Abstract Al-Ni alloys (for Ni< 45 at.%) show a unique property in that, over at least part of the
accessible undercooling range, the recalescence velocity measured in electromagnetically …

The present work is devoted to the phenomenon of induced side branching stemming from
the disruption of free dendrite growth. We postulate that the secondary branching instability …

We give an overview of contributions made to the computational phase-field modelling of
alloy solidification from the University of Leeds as part of the LiME project (EPSRC …

Polyhedral shapes can be found in crystalline materials ranging from macroscopic natural
mineral solids to microscopic or nanoscopic particles. These shapes originate from the …
