%X 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.
