A method for detecting local residual stresses in objects with a solid ion beam technique

A method for detecting local residual stresses in solid objects, in which a local material manipulation is performed on the solid object (7) by external energy and / or pulse action, which leads to a redistribution of stress and / or strain conditions in the solid object (7), wherein before and is made by the material handling in each case at least one recording of a hit by the material manipulation surface area of ​​the solid object (7), and caused from a comparison of the two photographs of the residual stress deformation fields on the surface (8) are determined, from which local residual stresses are derived can, characterized in that the local material manipulation is done with an ion beam (12) is with the a structure (14) is produced with dimensions at least in one dimension in the micro- or nanometer range in or on the solid object (7), and microscopic as receptacles admission n of the surface area made.
