Patent ID: 10001531

Abstract:
The present invention relates to a compound exhibiting Giant Magneto-Impedance (GMI) properties. The general chemical formula of the compound is (FeXCo100-X)100-(α+β+γ)CrαSiβBγ, characterized in that α<β and α<γ, wherein α is preferably in the range of 2 to 4% by weight, β is preferably in the range of 11.5% to 13% by weight, and γ is preferably in the range of 11% to 13% by weight, and X is preferably about 6% by weight. The chemical formula more preferably is (Fe6%Co94%)72.5%Cr2% Si12.5%B13%. The present invention also relates to a giant magneto-impedance (GMI) based sensing device for non-destructive contactless detection of carburization in austenitic stainless steel samples in field.
