利用二维Miedema坐标参数(△φ*和△n-1/3 ws)及加入尺寸因素△R/RA构成的三维化学坐标揭示了水溶液法制备多元合金的非晶形成规律.对109个合金分析表明,在二维和三维坐标中,可分别由一直线和一平面较好的将非晶形成和非形成区区分;非晶化条件为:二维坐标系中,二元系,|△φ*|＞6.4|△n-1/3 ws|+0.05;多元系,|△φ*|＞6.6|△n-1/3 ws|+0.05.判据的准确率在二元、二元和三元以及二元、三元和四元合金系中分别为:81.9%,82.9%及83.5%;三维坐标系中,二元系,|△R/RA|/0.6+|△φ*|/0.12-|△n-1/3 ws|/0.02=1,多元系,|△R/RA|/0.03+|△φ*|/0.1-|△n-1/3 ws|/0.01=1.在二元及二元和三元系统中,区分的准确率高于82%以及86%;该判据扩展至四元合金系后,准确率仍高于86%.
