摘要：

In this paper, the morphologies of AIP in Al-Si-P alloy were investigated in three-dimensional space (3-D space), and AIP hexagonal platelets with multiple twin planes were observed. Field emission scanning electron microscopy (FESEM) reveals that the thick AIP hexagonal platelets grew through the layer-by-layer growth mechanism of the thin hexagonal monolayer along the [111] direction. Meanwhile, the twin-related growth model was applied to explain the growth process of faceted AIP crystals.
