1. A method for non-destructive determining of material properties of electrically conductive components, comprising the acts of:

  • moving an electromagnetic eddy current testing sensor at least one of on and near a surface of at least one sample cast component in a manner producing a varying magnetic field in the sample cast component;

    sensing currents in the at least one sample cast component with the sensor;

    displaying in human-readable form a measurement signal indicative of the eddy currents resulting in the at least one sample cast component from the varying magnetic field;

    storing a reference eddy current measurement signal from a reference cast component with known impact-dynamic and/or crash-dynamic deformability;

    displaying in human-readable form the reference measurement signal with a gain of the reference measurement signal adjusted to a reference location in the display; and

    determining the relative impact-dynamic and/or crash-dynamic deformability of the at least one sample cast component relative to the impact-dynamic and/or crash-dynamic deformability of the reference cast component by comparing the displayed measurement signal of the at least one sample cast component to the displayed reference measurement signal,wherein the electromagnetic eddy current testing sensor is a high-resolution eddy current sensor adapted to a conductivity of the at least one sample cast component.
