Rapidly solidified ribbons of 50 μm and 100 μm in thickness were prepared by a single roll method. Al<sub>6</sub>Fe, Al<sub>12</sub>Mo and Al<sub>3</sub>Fe precipitates are observed in quenched specimens of 100 μm thick ribbons but hardly observed in those of 50 μm thick ribbons. Using the 50 μm and 100 μm thick ribbons, two kinds of alloy bar were produced by hot extrusion at 723 K. The alloy bar made from 100 μm ribbons shows a higher 1000 h creep rupture strength at 573 K∼673 K than the bar made from 50 μm ribbons. The "n" value calculated from the equation ε=<i>k</i>·σ<sup><i>n</i></sup> is 7 and 9 for the bars made from 50 μm and 100 μm ribbons, respectively.
