  • Giant magneto-impedance (GMI) based sensing device for the detection of carburization in austenitic stainless steel
    Patent number: 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-(?+?+?)Cr?Si?B?, characterized in that ?<? and ?<?, wherein ? is preferably in the range of 2 to 4% by weight, ? is preferably in the range of 11.5% to 13% by weight, and ? 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.
