%X The splat foils, 0.04--0.06 mm thick, of Al--RE (RE=Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Er, Yb) binary alloys were made by arc--melting and hammer--anvil technique at cooling rate in 10~6 K / s order of magnitude. The metastable extended solid solubilities of these RE elements have been evaluated by measurements of the lattice spacings of the rapidly solidified Al--RE alloys, they are 0.4, 0.15, 0.21, 0.21, 0.3, 0.5, 0.1, 0.6, 0.65, 0.7, 0.75, 0.2 at.--% for above mentioned individual RE metal, respectively. The secondary phase in rapidly solidified Al--RE alloys was identified to be Al_4RE for alloys containing light RE and Eu and Al_3RE for alloys containing heavy RE and Y. Some factors influencing the extension of solid solubility of Al--RE alloys were discussed.
