Abstract
An approach to determining the crash dynamic behavior of structural castings made of a AlSi10MnMg alloy in a simple and cost-effective manner is provided. In this approach eddy current testing is carried out using a high-resolution measuring coil which is adjusted to the cast-specific conductivity.
Claims8
A method for non-destructive determining of material properties of electrically conductive components, comprising the act 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 with the sensor eddy currents in the at least one sample cast component;
- and
- 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,
- wherein the electromagnetic eddy current testing sensor in a high-resolution eddy current sensor adapted to a conductivity of the at least one sample cast component.
