以溶质原子为中心, 并在第一配位壳层堆垛不同原子, 构造了一个新的原子密堆垛模型,用于预测像高溶质浓度Ti-Ni-Al等(伪)三元合金体系中玻璃形成能力最佳的合金.此模型不仅在Ti-Ni-Al, Ti-Ni-Sn等具有条带玻璃形成能力的三元体系中,而且在其它一些具有块体玻璃形成能力的体系中对玻璃形成能力最佳的合金成分预测结果与实验结果吻合良好.
A modified Miracle model based on packing different atoms on the first shell of solute–centered cluster is advanced to predict the best glass–former in some high content (pseudo–) ternary systems such as Ti–Ni–Al etc. The calculated results not only for the best ribbon metallic glass–formers in Ti–Ni–Al, Ti–Ni–Sn, but also for the best bulk metallic glass–formers in some other systems correspond to the experimental results very well, indicating the validity of this model.
