固液界面能的各向异性在凝固微观结构的形成过程中起着关键作用。利用 Cahn 和 Hoffman 的 Σ-矢量形式，该贡献展示了各向异性对晶体平衡形状和三重线表面张力平衡的影响。各向异性晶体的异质成核和枝晶生长形态的后果通过与 Al-Zn 和 Zn-Al 合金相关的具体例子进行了详细说明。
The anisotropy of the solid–liquid interfacial energy plays a key role during the formation of as-solidified microstructures. Using the ξ-vector formalism of Cahn and Hoffman, this contribution presents the effect that anisotropy has on the equilibrium shapes of crystals and on surface tension equilibrium at triple lines. Consequences for heterogeneous nucleation of anisotropic crystals and for dendritic growth morphologies are detailed with specific examples related to Al–Zn and Zn–Al alloys.
