Process for non-destructive materials testing
Abstract
The invention relates to a process for non-destructive materials testing, whereby a ferro-magnetic workpiece is magnetized in a periodic magnetic field and the signal of the remagnetization processes is measured inductively and, at the same time, the magnetic field is measured, whereby sound waves up to about 10 kHz are applied periodically to the workpiece by means of a mechanical vibrator.
