AI 中文摘要
本文建立了一个半经验动力学框架来预测快速凝固下多组分浓合金的相选择。该方法基于抑制竞争结晶途径所需的临界冷却速率，结合了BCC、FCC和HCP类结晶途径的拓扑依赖性排序以及玻璃形成能力校正。通过与实验和计算数据比较，表明该动力学准则能捕捉价电子浓度准则预期的晶格类型变化，描述相分离的动力学抑制并识别竞争性多相结晶，还能区分高低玻璃形成能力合金。为快速凝固多组分熔体动力学相竞争初步评估提供实用方法。
英文摘要
A semi-empirical kinetic framework is formulated for predicting phase selection in multicomponent concentrated alloys under rapid solidification. The approach is based on the critical cooling rate required to suppress competing crystalline pathways and combines topology-dependent ranking of BCC-, FCC-, and HCP-like crystallization pathways with a correction for glass-forming ability. The formulation includes a topology-dependent viscosity correction with a smoothed BCC multiplier and a continuous correction factor for glass-forming ability based on mixing enthalpy, excess entropy, and atomic-size dispersion. Comparison with experimental and computational data shows that the kinetic criterion captures changes in the lattice type expected from the valence electron concentration criterion, describes kinetic suppression of phase separation, and identifies competitive multiphase crystallization. The model also distinguishes alloys with high and low glass-forming ability. The proposed framework provides a practical approach for preliminary evaluation of kinetic phase competition in rapidly solidified multicomponent melts.
