Abstract: A method for enhancing inspection of components of specific geometry based on Barkhausen noises. The method includes specifying a first calibration curve that is independent of the component geometry, which describes the relationship between surface hardness values and measured Barkhausen noise signals. A first noise signal is determined by the measuring device for a reference component having the specified geometry and a first hardness value. A second noise signal is determined for a second reference component, having the specified geometry and a second hardness value lower than the first. A second calibration curve is determined, in which the first calibration curve is fitted to the first noise signal at the first hardness value and to the second noise signal at the second hardness value, such that using the second calibration curve, the measured noise signal of a component having the specified geometry relates with a surface hardness value.

Abstract: Discloses is a nondestructive inspection method of grain-boundary attack due to thermal sensitization in a chromium-containing nickel-based alloy, such as Inconel 600 alloy. The method comprises measuring a saturation magnetization Ms(Ti) of a test piece at each of a plurality of measuring temperatures defined by equally dividing a given measuring temperature range in the range of a minimum to a maximum of Curie temperatures corresponding to respective chromium concentrations in a chromium impoverished region of the alloy, and then quantitatively determining an average spatial distribution of the chromium impoverished region of the test piece, or the chromium-concentration-specific volume of the chromium impoverished region adjacent to the crystal grain boundaries of the test piece, according to a given calculation formula. The present invention can solve disadvantages in a conventional method of inspecting a chromium impoverished region of a chromium-containing nickel-based alloy, such as destruction of the alloy surface caused by an etching or breaking operation, which is incongruous with the philosophy of a nondestructive inspection, and poor information about chromium impoverished region, which is obtainable only in the alloy surface.

Abstract: A moving strip of sheet steel passes through a magnetic field that brings the magnetization in the sheet to effective saturation first in one direction and then in the other direction. As the sheet emerges from the applied field, the magnetization passes from the remanent value of one sign to the remanent value of the other sign. Sensing coils measures the flux change produced by passing from one remanent magnetization to the other and this flux change is halved to give the flux change necessary to reach a computed zero value of magnetization. The applied field necessary to maintain the magnetization in the sheet at the computed zero value represents the coercive force of the sheet, which is proportional to various mechanical properties of the steel such as the tensile strength. Instead of using remanent magnetization to compute the zero value, the sensing coils can be located within the applied magnetic field and the flux change produced by passing between the magnetization at saturation can be used.
