In order to improve the simple crystalline embryo model of amorphous metals proposed previously, the compositetype embryo model for amorphous Fe-B alloy is constructed on a computer by assuming that the b.c.c. like embryos andchemical clusters of Fe_3B type coexist. The interference function and pair correlation function are also calculated. Tomake a reasonable comparison with the experimental data, a new process of Fourier transformation, that takes accountof the truncation effect, is successfully applied to the structural model. The two functions are in good agreement with ex-periment when the embryo size is taken to be as small as 10 A in diameter corresponding to the 15 core atoms cluster. It isconcluded that the crystalline embryo model satisfactorily describes the amorphous structure.
