摘要: <正> 用计算机模式识别方法预测未知的合金中间相,是一种很有效的方法。用元素的价电子数Z、金属半径R、功函数φ等的函数张成多维空间,将已知金属间化合物绘入空间,用上述方法可以区分各种晶型的分布区域。据此可预报未知的合金中间相。我
Abstract:Some empirical rules governing the crystal type of AB_3 type alloy phases have been obtained by pattern recognition method. By computerized prediction, we have predicted that Dy-Ir, Gd-Ir and Nd-Ir systems form AuCu_3 type alloy phases. Based on this prediction, we have prepared Dy-Ir, Gd-Ir and Nd-Ir alloy samples and haste proved the existence of DyIr_3, GdIr_3 and NdIr_3 alloy phases, with AuCu_3 structure Their lattice parameters are: a=0.3842nm, a=0.3839nm and a=03836nm respectively.
