Abstract
The present invention relates to an amorphous alloy and a method for manufacturing thereof. The amorphous alloy according to the present invention includes has a chemical formula of Feioo-a-b-c-d-e-f-gCraMobCcBaYeMflg. Here, the M is at least one selected from a group consisting of Al, Co, N1 and Ni, and the I is at least one selected from a group consisting of Mn, P, S, and O as impurities. The a, b, c, d, e, f, and g are satisfied with the compositions of 16.0 wt %≦a<22.0 wt %, 15.0 wt %<b≦27.0 wt %, 2.0 wt %≦c<3.5 wt %, 1.0 wt %<d≦1.5 wt %, 1.0 wt %<e≦3.5 wt %, 0.25 wt %<f≦3.0 wt %, and 0.01 wt %≦g<0.5 wt %, respectively.
