Verfahren und Vorrichtung zur in situ-Ermittlung des Umwandlungsgrads einer nichtmagnetischen Phase in eine ferromagnetische Phase eines metallischen Werkstücks |
摘要 |
The invention relates to a method for the in situ determination of the degree of conversion of a non-magnetic phase in a ferromagnetic phase of a metallic work piece comprising an eddy current measuring method wherewith two distance measuring coils measure different distances to a work piece are measured using two distance measuring coils and distant dependent signals are determined. A distance dependent calculated value is determined therewith. A further measuring signal pertaining to a detector measuring coil is measured and a response field resulting from the application of an excitation field to a work piece is measured. A measured value for the degree of conversion is determined.
