Patent ID: 7815753

Claim:
A Fe-based multi-element bulk amorphous alloy composition represented by a formula of Fe a C β Si γ B x P y M a , in which α, β, γ, x, y, and a each represent atomic % of iron(Fe), Carbon(C), silicon(Si), boron(B), phosphorus(P) and a selected metal element respectively, in which α is 100-(β+γ+x+y+a) atomic %, where M is the selected metal element which is Ti, β is 9 atomic % or more and 11 atomic % or less, γ is 4 atomic % or more and 5 atomic % or less, x is 6 atomic % or more and 7 atomic % or less, y is 7 atomic % or more and 9 atomic % or less and a is 0.5 atomic % or more and 1.5 atomic % or less.
