Polycrystalline Fe-Mo-Si-B alloys with grains sized from 15 to 200 nm were prepared by means of the crystallization method. A critical phenomenon was observed in the variations of microhardness and electrical resistivity with respect to the annealing temperature. The critical temperature is 893 K which corresponds to the average grain size of 45 nm.

In Ni_(68)P_(18)Cr_(14) amorphous alloy, the dominant component elements Ni and P were in lower content in the surface layer, while Cr was enriched. There was a P enrichment region just below the surface oxide layer, which was supposed to enhance the surface segregation of Cr. Nickel was less oxidized than Cr.
